  • 製品の概要

    Abcam’s alpha 2 Macroglobulin Human in vitro competitive ELISA (Enzyme-Linked Immunosorbent Assay) kit is designed for the quantitative measurement of alpha 2 Macroglobulin in plasma and serum.


    An alpha 2 Macroglobulin specific antibody has been precoated onto 96-well plates and blocked. Standards or test samples are added to the wells and subsequently biotinylated alpha 2 Macroglobulin is added and then followed by washing with wash buffer. Streptavidin-Peroxidase Conjugate is added and unbound conjugates are washed away with wash buffer. TMB is then used to visualize Streptavidin-Peroxidase enzymatic reaction. TMB is catalyzed by Streptavidin-Peroxidase to produce a blue color product that changes into yellow after adding acidic stop solution. The density of yellow coloration is inversely proportional to the amount of alpha 2 Macroglobulin captured in plate.


    The entire kit may be stored at -20°C for long term storage before reconstitution - Avoid repeated freeze-thaw cycles.

Question
Answer

The lab has informed me that your sample collection method is fine and that the anti-coagulant will not affect the assay. You can include the anticoagulant.

Thank you for contacting us.

The lab said the other option besides sodium citrate 0.1M is the ready use tube that clinical lab used to draw
human plasma for your samples.


I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.

Question
Answer

Thank you very much for your call yesterday and for your patience while I've been in touch with my colleagues regarding this standard reconstitution volume.

For this lot, the standard vial contains 160 ug of human alpha-2-macroglobulin. So, to generate a stock solution of 40 ug/mL, you will need to reconstitute the standard in 4 mL of 1x diluent.

I hope this information will be useful, but if you have any further questions or need anything else, please let me know and I'll be happy to help.
