Product Overview
Product Name Anti-h PSA 8311 SPRN-1
Catalog Number 100103
Description Monoclonal mouse antibody, cultured in vitro under conditions free from animal-derived components.
Application FIA
Brand Medix Biochemica
Further Specification
Form/Appearance Liquid, may turn slightly opaque during storage
Concentration 1.0–1.1 mg/ml
Notes Clone 8311 reacts with non-reduced and reduced intact PSA but not with reduced PSA fragments (Rye et al., 1999). In the same study affinities for free-PSA and PSA-ACT-complex were, 1.7 x 10-10 mol/l and 1.55 x 10-10, respectively. They also noted that antibodies binding to epitope group 6 form a good pair with antibodies from groups 1 and 3. Clone 8311 crossreacts with human kallikrein-2 (Black, 1999b) and can be used to develop a hK2-assay.
