The principle of DPA/Tb3 for vesicle fusion assay is based on the fact that contact of the chelator dipicolinic acid (DPA) with terbium (III) forms an instant Tb3 -DPA complex that is ~10,000 times more fluorescent than free Tb3 . In the assay, separate vesicle populations are loaded with 2.5 mM TbCl3 in 50 mM...

Hepatitis C virus (HCV) genotype 1b, also known as HCV1b, is a fusion protein of a.a. 21-32 of NS4A, linker (4 a.a.) and a.a. 3-181 of NS3 (GenBank Accession No. AF054247) with Arg-to-Gln mutation on a.a. 155, and N-terminal Flag-His tag, MW = 22.3, expressed in an E. coli expression system.

Based on the unique mouse monoclonal Anti-cGMP antibody. It is the only EIA kit on the market with monoclonal anti-cGMP antibody (all other kits are based on polyclonal anti-cGMP antibodies). No more hazardous chemical (acetic anhydride ) for your cGMP assay. The monoclonal Anti-cGMP antibody has similar affinities...
