MBS906883 is a ready-to-use microwell, strip plate ELISA (enzyme-linked immunosorbent assay) Kit for analyzing the presence of the ectonucleoside triphosphate diphosphohydrolase 4 (ENTPD4) ELISA Kit target analytes in biological samples. The concentration gradients of the kit standards or positive controls render a theoretical kit detection range in biological research samples containing ENTPD4. The ELISA analytical biochemical technique of the MBS906883 kit is based on ENTPD4 antibody-ENTPD4 antigen interactions (immunosorbency) and an HRP colorimetric detection system to detect ENTPD4 antigen targets in samples. The ELISA Kit is designed to detect native, not recombinant, ENTPD4. Appropriate sample types may include undiluted body fluids and/or tissue homogenates, secretions. Quality control assays assessing reproducibility identified the intra-assay CV (%) and inter-assay CV(%).

ENTPD4 elisa kit
Principle of the Assay: This assay employs the quantitative sandwich enzyme immunoassay technique. Antibody specific for ENTPD4 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and any ENTPD4 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for ENTPD4 is added to the wells. After washing, avidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of ENTPD4 bound in the initial step. The color development is stopped and the intensity of the color is measured.

NCBI Summary for ENTPD4
This gene encodes a member of the apyrase protein family. Apyrases are enzymes that catalyze the hydrolysis of nucleotide diphosphates and triphosphates in a calcium or magnesium-dependent manner. The encoded protein is an endo-apyrase and may play a role in salvaging nucleotides from lysosomes. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene, and these isoforms may differ in divalent cation dependence and substrate specificity.

UniProt Comments for ENTPD4
UDPase: an ectonucleoside triphosphate diphosphohydrolase. Hydrolyzes preferentially nucleoside 5'-diphosphates; nucleoside 5'-triphosphates are hydrolyzed only to a minor extent. The order of activity with different substrates is UDP >> GDP = CDP = TDP; AMP, ADP, ATP and UMP are not substrates. Two splice variant isoforms have been described. Preferred substrates for isoform 2 are CTP, UDP, CDP, GTP and GDP, while isoform 1 utilizes UTP and TTP
