The LR³IGF-I Rapid™ ELISA Kit consists of a complete set of reagents and pre-coated plate to allow immediate assay of LR³IGF-I in culture media. Included in the kit are mouse monoclonal anti- LR³IGF-I capture antibody pre-coated onto an ELISA plate, standard LR³IGF-I protein, a biotinylated anti- LR³IGF-I detection antibody and horseradish peroxidase (HRP)-conjugated streptavidin. The addition of a substrate (3,3’,5,5’-tetramethylbenzidine, TMB) yields a coloured reaction product which is directly proportional to the concentration of LR³IGF-I present in samples and the supplied protein standard.

The Biosensis ApoE/Aβ Complex ELISA kit is a sandwich ELISA that allows the preferential measurement of ApoE/Aβ complexes. This kit consists of a pre-coated mouse monoclonal anti-Aβ capture antibody, a highly validated ApoE/Aβ complex standard that is pre-formed, lyophilised and ready for reconstitution, a biotinylated ApoE detection antibody, and horseradish peroxidase (HRP)-conjugated streptavidin and detection reagent. The addition of a substrate (3,3’,5,5’-tetramethylbenzidine, TMB) yields a coloured reaction product which is directly proportional to the level of ApoE/Aβ complex present in samples and protein standards. Importantly, a well-characteriaed and unique ApoE/Aβ complex is included as a standard. This complex is pre-formed and lyophilised, requiring only reconstitution with assay diluent prior to use.

AccuStart™ II PCR SuperMix is a 2X concentrated, ready-to-use reaction cocktail for routine PCR amplification of DNA fragments up to 4 kb. It contains all components, except primers and template. AccuStart™ II PCR SuperMix simplifies reaction assembly, improves assay reproducibility, and reduces the risk of contamination. A key component is AccuStart™ II Taq DNA polymerase which contains monoclonal antibodies that bind to the polymerase and keep it inactive prior to the initial PCR denaturation step. Upon heat activation (1 minute at 94 °C), the antibodies denature irreversibly, releasing fully active, unmodified Taq DNA polymerase. This enables specific and efficient primer extension with the convenience of room temperature reaction assembly.

The Mammalian β-Galactosidase Assay Reagent Kit is a simple and versatile assay to measure β-galactosidase activity in cultured mammalian cells. Cells grown on a plate may be lysed and tested for β-galactosidase activity by adding a single all-in-one lysis-and-assay solution. Alternatively, M-PER™ Mammalian Protein Extraction Reagent may be used to prepare lysate from washed adherent or pelleted cells, and then a portion of the lysate used to assay for β-galactosidase activity. With M-PER Reagent, there is no need to scrape cells or to perform freeze-thaw cycles. The remaining lysates prepared with M-PER™ Reagent may be used for applications such as reporter assays (luciferase, β-galactosidase and chloramphenical acetyltransferase), protein kinase assays (PKA, PKC, and tyrosine kinase), immunoassays (Western blot, ELISA, RIA) and protein purification.

The biuret and Lowry procedures are used for protein determination. The former is widely used for clinical assays. The latter, though more sensitive, is used for investigative work and is limited by poor stability of combined reagents, non-reproducibility of color, especially at low protein concentration, and nonlinear chromogenic response with protein concentration. Ohnishi and Barr modified the biuret reagent for the Lowry procedure, thereby simplifying it while improving the stability of the combined reagent.
