Generation of High Affinity Anti-Peptide Polyclonal Antibodies Recognizing Goat αs1-Casein

preparation of immunogen and purifica¬tion of high affinity and specificity fab fragment of anti-digoxin polyclonal antibodies

in this study we produced and purified a high titer of specific and high affin¬ity fab fragments of anti-digoxin antibody. immunization of rabbits with a conju¬gate of the cardiac glycoside digoxin, coupled by a periodate oxidation method to the amino group of lysine in bovine serum albumin resulted in the production of this type of high titer digoxin-specific antibodies with exceptionally high...

Allergic responses induced by goat milk αS1-casein in a murine model of gastrointestinal atopy.

Up to 3% of young children develop milk allergy and this may influence the development of immune-mediated diseases in later life. One protein that has been associated with allergic reactions to ruminant milk is α(S1)-casein (CN). Studies suggest that goat milk with low levels of α(S1)-CN may reduce allergenicity of milk, but the dose response to α(S1)-CN has not been confirmed. In this study, w...

Requirement of a Blocking Step in Affinity Purification of Polyclonal Antibodies

Second generation anti-MUC1 peptide monoclonal antibodies.

Second generation antibodies to mammary mucins were produced by immunizing mice with a peptide with a sequence deduced from that of the MUC1 complementary DNA sequence (PAHGVTSAPDTRPAPGSTAP). Four monoclonal antibodies (BCP7-10) were produced which gave different reactions. BCP8 was similar in tissue reactivity (by immunoperoxidase staining) to anti-breast cancer or anti-human milk fat globule ...

Presence of matrix-specific antibodies in affinity-purified polyclonal antibodies.

In general, antigen affinity columns made with commercially prepared activated affinity supports bind antibody specific for the coupled antigen. Nonetheless, in some cases affinity purification may yield antibodies to molecules other than the molecule of interest. In this report, we demonstrate such an occurrence: an antibody which adsorbs to an Affi-Prep 10 affinity matrix was found in the ser...
