Background

Erythropoietin (Epo) is a 30-kDa, heavily glycosylated protein produced primarily by the kidney. It is the principal factor that regulates erythropoiesis. The production of Epo by kidney cells is increased in response to hypoxia or anemia. The cDNAs for Epo have been cloned from many species. The mature proteins from the various species are highly conserved, exhibiting greater than 80% sequence identity at the amino acid level.

The biological effects of Epo are mediated by the Erythropoietin receptor (Epo R). At the protein sequence level, the human Epo R is approximately 83% identical to the mouse protein. As a result of alternative splicing of the Epo R gene, cDNA clones encoding truncated soluble forms of Epo R have been found. Recombinant soluble Epo R binds Epo with high affinity and is a potent Epo antagonist.

1. What is the difference between the Quantikine and Duoset ELISA kits?
   • Our Quantikine kits are fully optimized and validated for the sample types listed on the product specific webpage and datasheet, as this can vary between kits. Each kit is supplied ready to use with one pre-coated 96-well plate, a detection antibody directly conjugated to HRP, and all other necessary reagents. These kits are ideal for researchers who want the convenience of a ready to use and optimized ELISA product. Some of these kits are also available prepackaged in larger 6 and 50 plate sizes.Our DuoSet Kits, in contrast, are ELISA development kits containing the capture and detection antibody, the mass-value calibrated standard, and streptavidin-HRP to prepare approximately 5 or 15 plates. Ancillary reagents will need to be used/purchased, and for most kits, we will recommend one of our Ancillary Reagent Kits, which contain the reagents we use ourselves in-house. DuoSet kits are validated only for cell culture supernatant samples and therefore require further development and validation for accurate measurement in more complex samples such as serum and plasma. Our DuoSet Kits offer an economical, flexible alternative for the experienced ELISA user.
