Kremen-1 BioAssay(TM) ELISA Kit (Mouse)

Kremen protein 1 is a protein that in humans is encoded by the KREMEN1 gene. This gene encodes a high-affinity dickkopf homolog 1 (DKK1) transmembrane receptor that functionally cooperates with DKK1 to block wingless (WNT)/beta-catenin signaling. The encoded protein is a component of a membrane complex that modulates canonical WNT signaling through lipoprotein receptor-related protein 6 (LRP6). It contains extracellular kringle, WSC, and CUB domains. Alternatively spliced transcript variants encoding distinct isoforms have been observed for this gene. Sample Type: Cell lysate, cell culture supernates, serum, plasma (Heparin or EDTA). Intended Use: Sandwich High Sensitivity BioAssay(TM) ELISA kit for Quantitative Detection of Mouse Kremen-1. Sensitivity: <10pg/ml, Range: 125pg/ml-8000pg/ml, Specificity: Recognizes natural and recombinant Mouse Kremen-1. There is no detectable cross-reactivity with other relevant proteins. Test Principle: This Mouse Kremen-1 BioAssay(TM) ELISA Kit was based on standard sandwich enzyme-linked immune-sorbent assay technology. A specific for Kremen-1 has been precoated onto 96-well plates. Standards(Expression system for standard: NSO, Immunogen sequence: A20-G395) and test samples are added to the wells, a biotinylated detection specific for Kremen-1 is added subsequently and then followed by washing with PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex was added and unbound conjugates were washed away with PBS or TBS buffer. HRP substrate TMB was used to visualize HRP enzymatic reaction. TMB was catalyzed by HRP to produce a blue color product that changed into yellow after adding acidic stop solution. The density of yellow is proportional to the Mouse Kremen-1 amount of sample captured in plate.
