|Product Name||Human A2M/Alpha2-Macroglobulin PicoKine™ ELISA Kit|
|Description||For quantitative detection of human A2M in cell culture supernates, cell lysates, serum and plasma (heparin, EDTA).|
|Cite This Product||Human A2M/Alpha2-Macroglobulin PicoKine™ ELISA Kit (Boster Biological Technology, Pleasanton CA, USA, Catalog # EK1118)|
*Our Boster Guarantee covers the use of this product in the above tested applications.
**For positive and negative control design, consult "Tissue specificity" under Protein Target Info.
|Immunogen||Expression system for standard: from human plasma|
|Cross Reactivity||There is no detectable cross-reactivity with other relevant proteins.|
*Sensitivity, or Lower Limit of Detection (LLD), is the minimum level of target protein the ELISA assay can detect. We measure 20 blank wells and if the O.D. value is 2 standard deviations higher than the blanks' average O.D. the sample can be deemed positive.
*This assay range is determined using common samples. For samples with low target protein concentrations, users can adjust the standard curve to extend the lower limit of assay range.
|Sample Type||cell culture supernates, cell lysates, serum and plasma (heparin, EDTA).
*The above listed samples are the ones valided with the assay. If you do not see your sample of interest listed, as long as there is enough level of target protein present in the sample, this Picokine™ ELISA kit should detect it.
**For protocol and tips regarding preparing your sample of interest, please check our ELISA sample preparation guide.

You can check the tissue specificity below for information on selecting positive and negative control.
|Molecular Weight||163291 MW|
|Protein Function||Is able to inhibit all four classes of proteinases by a unique 'trapping' mechanism. This protein has a peptide stretch, called the 'bait region' which contains specific cleavage sites for different proteinases. When a proteinase cleaves the bait region, a conformational change is induced in the protein which traps the proteinase. The entrapped enzyme remains active against low molecular weight substrates (activity against high molecular weight substrates is greatly reduced). Following cleavage in the bait region a thioester bond is hydrolyzed and mediates the covalent binding of the protein to the proteinase.|
|Tissue Specificity||Secreted in plasma. .|
|Sequence Similarities||Belongs to the protease inhibitor I39 (alpha-2- macroglobulin) family.|
|Subcellular Localization||Secreted .|

Typical Data Obtained from Human A2M/Alpha2-Macroglobulin PicoKine™ ELISA Kit
(TMB reaction incubate at 37°C for 15-20min)
*The typical data is obtained from Boster's internal QC result and for reference only. It may differ from the lab test results of the end users. It is more important that the user's lab test results reflect the same linearity demonstrated in the typical data than achieving exactly the same O.D. values.
