Can it detect albumin?

Thanks for your inquiry. Yes it can detect albumin.

We currently use your HSA ELISA kit and I was wondering if you could advise as to whether any of the constituent reagents contain Sodium Azide (NAN3).

Thanks for your inquiry.
There is no constituent reagents containing Sodium Azide (NAN3) in our kit.

Target Background

(From Uniprot)
Binds water, Ca(2+), Na(+), K(+), fatty acids, hormones, bilirubin and drugs (Probable). Its main function is the regulation of the colloidal osmotic pressure of blood (Probable). Major zinc transporter in plasma, typically binds about 80% of all plasma zinc. Major calcium and magnesium transporter in plasma, binds approximately 45% of circulating calcium and magnesium in plasma. Potentially has more than two calcium-binding sites and might additionally bind calcium in a non-specific manner. The shared binding site between zinc and calcium at residue Asp-273 suggests a crosstalk between zinc and calcium transport in the blood. The rank order of affinity is zinc > calcium > magnesium. Binds to the bacterial siderophore enterobactin and inhibits enterobactin-mediated iron uptake of E.coli from ferric transferrin, and may thereby limit the utilization of iron and growth of enteric bacteria such as E.coli. Does not prevent iron uptake by the bacterial siderophore aerobactin.
