High-Performance AAS for Fully Automated Graphite AAS with Zeeman and Deuterium Background Correction

ICP-MS Tailored to Your Requirements

Bovine serum albumin (BSA) is used extensively as a carrier protein to dilute antibodies and as a general protein blocking agent in immunoassays and immunodetection protocols. Our IgG-free BSA, which is also protease-free, should alleviate many of the problems associated with using BSA. Many preparations of BSA, even some of the highest purity grades, contain IgG that may become an antigen for cross-reacting secondary an…

ChromPure is our trade name for highly purified proteins from the serum of non-immunized animals.

Antisera to Enzymes, Serum Proteins, & Whole Serums. Polyclonal antisera from immunized hosts are lipid extracted to improve clarity, salt fractionated, dialyzed against phosphate buffered saline containing sodium azide, and freeze-dried. Antisera against whole serums are obtained by immunizing host animals with whole serum. Antisera against whole IgG molecules [i.e. Anti-IgG (H+L)] are recommended for bridging PAP to prima…

Solid-Phase Immunoadsorbent Gels. Highly purified IgG from the serum of non-immunized animals is coupled to cyanogen bromide-activated 4% agarose gels for use in preparing affinity-purified antibodies or removing cross-reactive antibodies. Proteins are coupled at a concentration of 1 mg protein per ml of settled gel, and are packaged in phosphate buffered saline with sodium azide.

Peroxidase-Anti-Peroxidase (PAP) Soluble Immune Complexes. Whole antisera against IgG (H+L) are recommended for bridging PAP to primary antibodies. Antisera against IgG (H+L) or against the F(ab') 2 fragments of IgG will also bridge PAP to IgM primary antibodies (such as IgM monoclonal antibodies) by virtue of common light-chain recognition.
