Biolegend, 442708, LEGEND MAX™ Mouse Erythropoietin (EPO) ELISA Kit, 5precoatedplates

Erythropoietin (EPO) is the most important hormone regulating erythropoiesis. It is a glycoprotein also known as hematopoietin. EPO is mainly produced by kidney and liver in response to hypoxia to induce red blood cell production. Mouse EPO is a secreted protein of 166 amino acids with a predicted molecular mass of ~18.6 kD. However, it migrates on SDS-PAGE at ~33-48 kD due to heavy glycosylation. EPO is closely related to thrombopoietin (TPO) and highly conserved across species, with mouse EPO being 95% and 80% identical to rat and human, respectively. EPO functions through binding to its receptor, EPO R, a homodimer, on erythoid precursors, and promotes their differentiation and maturation. As expected, serum levels of EPO are elevated in response to various conditions that result in tissue hypoxia (e.g., blood loss, high altitude, cardiac or pulmonary disease, and anemia). Increased EPO levels can also be due to increased production by cancer cells of the liver and kidney. Decreased levels of EPO are often seen with chronic renal failure and other chronic diseases, which causes anemia. Mouse endogenous EPO and recombinant EPO share the same amino acid sequence, with differences in the glycosylation profiles. The LEGEND MAX™ Mouse EPO ELISA kit is a Sandwich Enzyme-Linked Immunosorbent Assay (ELISA) with a 96-well strip plate that is pre-coated with a rat monoclonal anti-mouse EPO antibody. The Detection Antibody is a biotinylated polyclonal goat anti-mouse EPO antibody. This kit is specifically designed for the accurate quantitation of mouse EPO from cell culture supernatant, serum, plasma (heparin), tissue homogenates and other biological fluids. This kit is analytically validated with ready-to-use reagents.

Q: In your LEGEND MAX™ ELISA Kits, there is a step that calls for washing the plates before adding sample. What is the purpose of this step?
A: We typically use a stabilizer for pre-coated plates. The additional washing step is designed to remove these components before you start the assay. If you do not perform the washing, the effect on assay performance is negligible.
Q: I have multiple LEGEND MAX™ ELISA kits that I want to run simultaneously. Can I use the same wash buffer for all the kits?
A: The wash buffer provided in all our LEGEND MAX™ kits is the same and the part numbers on the wash buffer bottles in these kits should be identical. For ELISA MAX™ Deluxe and ELISA MAX™ Standard Sets, we provide a recipe for the wash buffer on each kit’s technical data sheet. This recipe is the same for all ELISA MAX™ sets.
Q: For some of your ELISA kits, why do my serum samples require dilution with assay buffer?
A: In some cases, dilution with assay buffer is required to minimize the matrix difference between the samples and the standards to achieve better accuracy.
