ELISA kit description
GENTAUR's human Endostatin ELISA test is a ready to use ELISA kit. We use a monoclonal from mouse specific for Endostatin was used as capure antibodies on the ELISA test plate. The internal standards (E.coli, H1154-S1335) and your samples are measured with a biotin conjugated polyclonal from goat specific for Endostatin will than be washed with PBS. The colour reaction with TMB on HRP will colour the well from blue to yellow with the stop solution. The more human Endostatin in your sample the higher the ELISA signal will be compared to this elisa's standard curve.

How the elisa works
Sample the amount of 100ul/well of the standard solution at 10000pg/ml, 5000pg/ml, 2500pg/ml, 1250pg/ml, 625pg/ml, 312pg/ml, 156pg/ml human Endostatin standard solutions into the precoated 96-well plate. Add 0.1ml of the sample diluent buffers into the control well (Zero well). Add 0.1ml of each properly diluted sample of human cell culture supernatant, serum, plasma(heparin, EDTA) or human milk to the ELISA plate. Keep in mind that each human Endostatin standard solution and each sample be measured in duplicate.

More gene info
Endostatin is a naturally-occurring 20-kDa C-terminal fragment derived from type XVIII collagen. It is reported to serve as an anti-angiogenic agents, similar to angiostatin and thrombospondin. And it is produced by proteolytic cleavage of collagen XVIII, a member of the multiplexin family that is characterized by interruptions in the triple helix creating multiple domains, by proteases such as cathepsins. Using a genomic clone as a probe for fluorescence in situ hybridization, Endostatin was mapped the COL18A1 gene to 21q22.3. By immunoprecipitation analysis using membrane fractions of human mammary epithelial cells, It showed that endostatin specifically bound to cell surface nucleolin with high affinity. Blockage of nucleolin with neutralizing antibodies or knockdown of nucleolin by RNA interference countered the antiendothelial activity of endostatin and abrogated its antiangiogenic and antitumor activity in vivo.

Technique
ELISA kit, ELISA, ELISAs Enzyme-linked immunosorbent assay 90320007 SNOMED code are used by the medical researcher for detection of human, mouse, … proteins are supplied in coated 96 well plates to be stored at +4°C. ELISA test kits can be sandwich ELISA. In sandwich ELISAS Enzyme-linked immunosorbent assay 9we use captor and detector antibodies. In single antibody ELISAs the antigen is coated and only a detector antibody is used. Traditional competition antigen ELISAs are coated with a captor antibody and a competitive antigen is labelled with the chromogen. In this case the ratio on your graph will be inverse proportional with the antigen present in your sample.
