6. BRIEF RESUME OF THE INTENDED WORK

6.1 Need For Study

Polyclonal antibodies are typically produced by immunization of a suitable mammal, such as a mouse, rabbit or goat. Larger mammals are often preferred as the amount of serum that can be collected is greater. An antigen is injected into the mammal. This induces the B-lymphocytes to produce IgGimmunoglobulin specific for the antigen. This polyclonalIgG is polyclonal purified from the mammal’s serum1.

Many methodologies exist for polyclonal antibody production in laboratory animals. Institutional guidelines governing animal use and procedures relating to these methodologies are generally oriented around humane considerations and appropriate conduct for adjuvant that is agents which modify the effect of other agents while having few if any direct effects when given by themselves use2. This includes adjuvant selection, routes and sites of administration, injection volumes per site and number of sites per animal. Institutional policies generally include allowable volumes of blood per collection and safety precautions including appropriate restraint and sedation or anaesthesia of animals for injury prevention to animals or personnel1.

The primary goal of antibody production in laboratory animals is to obtain high titer, high affinity antisera for use in experimentation or diagnostic tests. Adjuvants are used to improve or enhance an immune response to antigens. Most adjuvants provide for an injection site, antigen depot which allows for a slow release of antigen into draining lymph nodes.

Such antigens by themselves are generally poor immunogens. Most complex protein antigens induce multiple B-cell clones during the immune response, thus, the response is polyclonal. Immune responses to non-protein antigens are generally poorly or enhanced by adjuvants and there is no system memory8.

Recent investigation showed that polyclonal antibodies, which is raised against mycobacterium toxoid, was used in used to detect mycobacterium in tissue with the use of immunohistochemical techniques, as vitamins are must for the production of antibodies, the production of antibody can be enhanced by studying, immunizing animal, with vitamins, and without vitamins, and injecting along with adjuvants, and can be detected by the Method of ELISA.

Use of polyclonal antibodies against carcinogen-DNA adducts in analysis of carcinogenesis.

6.2 Review Of Literature

1. LI QY. etal., ExtractedGliadins from three wheat varieties, viz., Henan and Nongda, were used as antigens to immunize in BALB/C mice, and the corresponding polyclonal antibodies were prepared, designated as Anti-A, Anti-B, Anti-C, Anti-Aa, Anti-Ab, Anti-Ag and Anti-Av, respectively. Of seven polyclonal antibodies tested, three (Anti-Ag, Anti-Av and Anti-A) displayed significant positive or negative associations between antibody binding and dough development time, strength, valorimenter value and stability time, but no significant correlations were observed with water absorption. These results suggest that polyclonal antibodies could be used for rapid prediction and screening of wheat quality paraK4.

2. Folwarczna J. etal., Reported the gene encoding the coat protein (CP) of a potato virus Y (PVY) was cloned into expression vector pMPM-A4Ω. PVY CP was expressed in Escherichia coli and the purified recombinant protein was used for raising rabbit polyclonal antibodies. The sera and antibodies were tested for the detection of PVY in the laboratory host Nicotiana tabacum CV. Petit Havana SR1 and in various cultivars of the natural host Solanum tuberosum by ELISA as well as by Western blots. The antibodies can be used for the detection of the whole strain spectrum of PVY by indirect plate trapped antigen ELISA and Western blot, but not by double antigen sandwich ELISA5.

3. Michael K. Schunk et al., Found the Immunization introduces an external substance to induce the host immune system to respond specifically. Typically an antigen is used, but DNA, or a primed, pre-existing leukocyte or antigen presenting cell, can also be used. Immunization is currently being used or investigated for the prevention and treatment of infectious diseases, cancer, addictions, allergies, pregnancy, and autoimmune diseases. The choice of immunization protocols is complex, and results may be affected by many factors such as dose and concentration of antigen, choice of adjuvants, time between inoculation and response measurement, and method of detection. The immune system responses to an antigen are also complex and continue to develop with advancing age. Anatomical, physiological, and immune system differences between species influence responses to immunization, as do the purity and presentation of the antigens and adjuvants. When directly comparing results, animals should be sourced from the same supplier. This review highlights the many uses of immunization techniques and introduces important considerations for the choice of protocols and animal models6.

4. Padmavathy L, et al., A study was undertaken to evaluate the utility of immuno-histochemical staining to demonstrate Mycobacterium tuberculosis antigen in tissue sections. This is based on the finding that the mycobacterium antigen is the last to disappear from the tissues and thus can be used as a marker of mycobacterial infections. Mycobacterial antigen was demonstrable in majority of cases of cutaneous tuberculosis using polyclonal antiserum. This test by itself cannot be considered as diagnostic. The results should be considered along with other findings7.

5. Simona,Montietal M, etal., Fusaproliferin (FP), a toxic metabolite of the world-wide maize pathogens Fusarium proliferatum and Fusarium subglutinans, was recently found to be a natural contaminant of maize. FP-hemiglutarate conjugated to modified bovine serum albumin was synthesized, characterized, and used as an antigen for raising polyclonal antibodies by immunizing rabbits. Indirect and competitive ELISA and immunoblotting analyses were performed to determine antibody specificity towards the mycotoxin. The determination of 10 µg of free FP/mL was achieved using antibodies purified by means of affinity chromatography on a FP-lysine-Sepharose column. This unsatisfactory detection limit is due to high background values; thus, this method is not competitive with traditional UV-HPLC methods.

6. Deepa Arora, et al., Reported reduced antibody response to tetanus toxoid (‘VT) was previously demonstrated during vitamin A deficiency but the response to bacterial lipopolysaccharide (LPS) was normal. We addressed whether anti-TT IgG responses are enhanced in vitamin A-sufficient and deficient rats by immunization with LPS plus TI’. Antibody responses in vitamin A-sufficient and deficient rats increased significantly after co immunization8.

7. Pasatiempo, Immunized the rats with polysaccharide antigens from Streptococcus pneumoniaor Neisseria men ingitidis, antibody production did not exceed 0-19% of the response of control rats. Vitamin A depletion also severely compromised the response to two T cell-dependent antigens, tetanus toxoid and sheep red blood cells. In striking contrast, retinol-depleted rats immunized with lipopolysaccharides from Pseudomonas aeruginosa and Serratia marcesens produced an antibody response indistinguishable from retinol-sufficient animals. These lipopolysaccharides could elicit antibodies in rat pups, whereas the capsular polysaccharide antigens could not9.to homogeneity from bovine

8. Hardy D et al.,Found,mice (Sobey) bred to select lack of antibody production against bovine serum albumin have been examined for their responsiveness over a wide range of antigen doses. With low doses of antigen both Sobey mice and an out bred line of Swiss White mice produce similar amounts of antibody. Antigen in amounts greater than 500 yg produce tolerance more effectively in Sobey mice and this is the reason for their unresponsiveness at high antigen dose levels11.
