S100A8 (also MRP8 and calgranulin A) is a 10 kDa member of the S100 family, EF-hand superfamily of Ca-binding proteins. It is produced by neutrophils and monocytes, and forms Ca2+-dependent heterodimer/heterotetramer complexes (termed calprotectin) with S100A9. It functions both intracellularly and extracellularly, where it binds to RAGE and CD36. Human S100A8 is 93 amino acids (aa) in length. It contains two EF-hand motifs (aa 12 - 47 and 46 - 81) and one high-affinity Ca2+-binding site (aa 59 - 70). There may be one splice form that shows a 15 aa substitution for the C-terminal 14 amino acids. Although mouse S100A8 is cleaved by MMP-2 after Asn21, it is unclear if human S100A8 is susceptible. Full-length human S100A8 is 57% and 74% aa identical to mouse and canine S100A8, respectively.

Sample Tested: Serum and PlasmaVerified Customer | Posted 03/11/2022Used this kit for quantifying mouse S100A8 in serum samples but did not see any detecting in our samples. Standard curve looks good.Bio-Techne ResponseWe have been in touch with the customer to resolve this issue according to our Product Guarantee and to the customer’s satisfaction. DuoSet kits are validated for cell culture supernatants. Working with other type of samples may require some empirical validation because factors like sample matrix etc. can impact antibody binding. We recommend to perform Spike, Recovery, and Linearity tests to optimize the conditions for any other sample types.
