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.

Supplier: Biosensis

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.

Ionic detergent compatibility reagent for Pierce™ 660 nm protein assay kit, 5×1 g

Supplier: Quantabio

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.
