Aurora Biomolecules dedicates to peptide synthesis (and polyclonal antibody production) for any small quantity purpose. FMOC chemistry (on Perceptive Biosystems Pioneer instruments) is used for peptides synthesis Online monitoring of the coupling efficiencies and HATU activation helps insure that the major component of the synthesis is the correct oligopeptide. Purification is firstly carried out by size exclusion chromatography, and then by HPLC on a PE vision purification workstation. Typically, 20 mg of pure peptide are obtained. The molecular weight of the purified peptide is determined as a final confirmation of quality. 

Polyclonal antibodies are obtained directly from the serum of the immunized animals (sometimes a purification step is carried out before their use). A family of clones is obtained that recognize the global structure of the hapten immunized, exhibiting each clone to a specific binding to different epitopes in the molecule. Therefore, the affinity of a PAb will be a combination of the... 

Due to the importance of this technology for protein expression, manufacturers Sigma, Serotec, Abeam and many others offer a wide range of products for the detection, isolation and purification of tagged proteins. These vendors also provide monoclonal and polyclonal antibodies specific for the most commonly... 

The preparation of chiral alcohols can be carried out very simply because the regeneration of NADPH is possible by the addition of isopropanol. Unpurified crude extract samples of the ADH from L. kefir were found to be a useful catalyst for the synthesis of (P)-alcohols [160] some examples for the preparation of some chiral alcohols using this enzyme are given in Table 8. Though this ADH becomes unstable to such a degree during the purification process, enough material of the pure enzyme could be prepared to produce polyclonal antibodies and to screen for related (R)-specific enzymes. 

With the advent of affinity chromatography to isolate enzymes [7] it was possible to adapt the method for the isolation of antibodies [8], The purification of many types of anti-carbohydrate antibodies with specificity for carbohydrate residues of macromolecules has been achieved. The antibodies were isolated by affinity chromatography on adsorbents with proper ligands. The immunodeterminants of the antigens have been found to be mono- or disaccharide residues of the antigen. The anti-carbohydrate antibodies with unique properties are useful in a variety of medicinal and technological applications. In this article the emphasis is on polyclonal antibodies specifically the preparation, properties and uses of anti-carbohydrate antibodies.
