r-bZP3 was arsanilated using a modification of the procedure of Nisnoff (1967). Briefly, arsanilic acid (100 mg) was dissolved in 5 ml of I M HCI. A IO ml stock of NaN02 (10 mg/ml) was also prepared fresh and added dropwise to the arsanilic acid solution while vortexing. Activation of arsanilic acid was checked on starch-KI paper. The ice cold activated arsanilic acid solution was added dropwise to the protein solution (5 mg of r-bZP3 in 100 mM PB, pH 7.4) stirring constantly in an ice water bath, while pH was maintained between 9.0 and 9.5 with 10 N NaOH. The protein solution was dialyzed extensively against I 00 mM PB having 4 M urea. Arsanilation of r-bZP3 was checked by ELISA using ars-r-bZP3 for coating ( 1 flg/well) and using a 1:100 dilution of murine anti-ars MAb, R 16.7 (Durdik et al., 1 989). Bound Ab was revealed using anti-mouse HRPO conjugate (I :5000). Three monkeys previously immunized with r-bZP3-DT conjugate (MRA-375, MRA-640 and MRA-672) and 2 naive monkeys (MRA-446 and MRA-670) were immunized at 2 intramuscular sites with 250 flg of ars-bZP3 conjugate using Squalene:Arlacel A ( 4: 1) as an adjuvant. Boosters were administered at intervals of 20 days and bleeds were collected I 0 days post immunization. Bleeds were analyzed by ELISA using r-bZP3 and ars-BSA for coating to determine anti-bZP3 and anti-ars Ab titres as described earlier.

Arsanilation of r-bZP3

Cells and supernatant collected 72 h pi were analyzed on a 0.1% SDS-I 0% PAGE and Western blot using polyclonal Abs generated in rabbit against peptide-DT conjugates using (i) 23-45 aa residue N-terminal peptide with an extra lysine at the N-terminus (KQPFWLLQGGASRAETSVQPVLVE), (ii) 300-322 aa residue C-terminal peptide (CSFSKSSNSWFPVEGPADICQCC) corresponding to the bZP3 sequence (iii) MA-451 and (iv) goat anti-GST Ab. The C-terminal anti-peptide Ab was used for determining whether or not the full length bZP3 was being expressed by the cells infected with the different viruses. Anti-mouse (I :500), anti-rabbit ( 1 :500) or anti-goat ( 1 :500) Abs conjugated to HRPO were used for revealing bound Ab.

Cells were pelleted down, and resuspended in fresh PS medium at an OD600of 0.6. Next, 100 μl culture was inoculated in 4 ml PS medium with or without streptonigrin. Streptonigrin was added to a final concentration of 0.1μg/ml into

insert of 1:3 for sticky end ligations. Ligation mix was incubated either at 22°C for 30 min or 16°C for 14-16 h. After incubation, T4DNA ligase was inactivated at 65°C for 20 min

After restriction enzyme digestion, digested products were resolved on agarose gels, and desired DNA fragments were extracted from the gel. Otherwise digested DNA fragments were precipitated by Phenol-choloroform-isoamyl alcohol method. Concentration of gel extracted or precipitated fragments were determined using spectrophotometer and ligation reactions were set up using a molar ratio

The reaction mixture contained 10 μl of culture filtrate, 490 μl of double distilled water (DDW) and 300 μl of methanolic rhodanine solution. This mixture was incubated for 5 min at 30°C in a water bath. The reaction was stopped by adding 0.3 ml of methanolic rhodanine solution (0.667 %), which resulted in the formation of complex between gallate and rhodanine. This was followed by the addition of 0.2 ml of KOH solution (0.5N) and the tubes were further incubated at 30°C for 5 min. The total reaction mixture in each tube was diluted with 4.0 ml of distilled water. Tubes were further incubated at 30°C for 10 min. The absorbance was measured at 520 nm against a control having distilled water in place of culture filtrate. The absorbance thus obtained was used to calculate the amount of gallic acid present in the culture filtrate, from the standard gallic acid curve prepared in the range of 100-1000 μg/ml.

The procedure of Sharma et al. (2000) was used to estimate the gallic acid in the culture filtrate. Reagents: Methanolic rhodanine solution (0.667% w/v): Prepared by dissolving 0.667 g of rhodanine in 100 ml of methanol.Potassium hydroxide (0.5 N): 2.8 gpotassium hydroxide dissolved in100 ml of distilled water.

For Yeast colony PCR, yeast cells were subjected to zymolyase (MP Biomedicals, 0832092) digestion to obtain thespheroplast. To perform zymolyase digestion, a digestion cocktail was prepared in 1XPBS consisting of zymolyase (2.5mg/ml) and sorbitol (1.2 M). The cocktail was dispensed in 0.2ml PCR tubes in 10 μl aliquots anda tip-full of yeast cells wasadded to these tubes. Tubes were incubated at 37°C for 2-3 h and 1 μl of digested mixture was used as a template in a PCR reaction

dropped on clean prechilled slides held at a 45°angle from a height of 18 inches, dried at 55°Con a hot plate and stained with 3% geimsa in phosphate buffer (pH 6.8) for 10 min. Slides were washed three times and dried, individual metaphase spreads were analyzed using bright field microscopy (Zeiss Axio Scope), and chromosomal aberrations were scored manually from each spread

MEFsplated in 6 cmdishes were treated with MMC (300 nM) for 12 h. Post damage cells were treated with colcemid (0.1 μg/mL) for 4 hto arrest cells in metaphase. After 4 h cells were washed twice with PBS to remove traces of colcemid and harvested by trypsinisation, pelleted down at 100 x g for 5 min in 15 mL conical tubes. The supernatant was removed by leaving 0.5 mL and resuspended thoroughlyby pippeting. Cells were subjected to hypotonic swelling in pre-warmed 0.075 M KCl for 15 min at 37°C[Note: key to this step is to add hypotonic solution drop by drop slowly otherwise cell clumps will form which are impossible to disperse. Add a few drops first then pipette the cells up and down to mix them thoroughly and add few more drops. Invert tubes 2-3 times during the incubation]. After 15 min cells were fixed by adding few drops of chilled fresh fixative (methanol: glacial acetic acid; 3:1) kept in the deep freezer. Cells were pelleted down at 100 x g for 8 min, the supernatant was removed, 0.5 mL of fixative was left behind and the pellet was resuspended very gently. Slowly fresh fixative was added in the same manner as the KCl solution and cells were pelleted down at 100 x g for 8 min; this step was repeated twice. The supernatant was removed by leaving 0.5 mL fixative and the cells were resuspended and mixed well before preparing metaphase spreads. Cell suspensions were

Sectional interest and animosity will deepen the irritation, and all hope of remedy is rendered vain, by the fact that public opinion at the North has invested a great political error with the sanction of more erroneous religious belief.

MR. CORNELLIER—All the confederations which you have mentioned were or are republican, and had the common fate of republican institutions. You have not said a word about monarchical confederations. MR. JOLY—I have made no mention of monarchical confederations, because none have ever existed, and none can exist. The principle of a monarchy is that the power resides in one person; the principle of confederation is that it resides in all the members of the confederation. A confederation would, therefore, always be a republic, even if formed of several states subject to a monarchy; because the power would not be vested in one person, but in each of the several states, of which no one would acknowledge a head ; it would be a republic consisting of a very small number of members. Before I take leave of all the confederations, the names of which I have mentioned, I intend to say one word, at least, in their favor. We understand that states

The Prime Minister stated that the object of Confederation was to strengthen the monarchical principle in this country. I do not see that it is necessary to confer upon the Crown greater privileges than it already possesses in England itself. In England the members of the House of Lords are not appointed by the Crown ; succession in the peerage goes down hereditary from father to son ; but here it is proposed that the members of the Legislative Council, which body corresponds to the House of Lords, should be selected by the Crown. Why should this be ? Why go beyond what is done in England itself? Is it that the Crown complains that it has not sufficient power here ?

The human character is susceptible of other incitements to correct conduct, more worthy of employ, and of better effect. Pride of character, laudable ambition, & moral dispositions are innate correctives of the indiscretions of that lively age; and when strengthened by habitual appeal & exercise, have a happier effect on future character, than the degrading motive of fear; hardening them to disgrace, to corporal punishments, and servile humiliations, cannot be the best process for producing erect character. The affectionate deportment between father & son offers, in truth, the best example for that of tutor & pupil

Because many of the theories deal with issues of power, students on the margin for particular reasons--ethnicity, class, ability--;ire often more receptive to the basic ideological premises of these theories than are their more privileged peers, who sometimes respond to theories such as gender and class as using the master's tools to dismantle the tnaster's house.
