The Proteome Profiler Human Phospho-Immunoreceptor Array Kit is a membrane-based sandwich immunoassay. Capture antibodies spotted in duplicate on nitrocellulose membranes bind to specific target proteins present in the sample (Step 1). Tyrosine phosphorylation of the captured proteins is detected with an HRP-conjugated pan phospho-tyrosine antibody (Step 2) and then visualized using chemiluminescent detection reagents (Step 3). The signal produced is proportional to the amount phosphorylation in the bound analyte.
Determining the phosphorylation of multiple immunoreceptors in a single sample can be expensive, time consuming and can require specialized equipment. Performing multiple immunoprecipitations and Western blots requires time, labor, and reagents. The use of a multiplex antibody array to detect multiple phosphorylations in a single sample can be cost-effective and also save time and sample.
This kit contains the following azide-free, fluorochrome-conjugated antibodies to verify human stem cell pluripotency:

Figure 1A: The Human Phospho-Immunoreceptor Array detects multiple tyrosine phosphorylated immunoreceptors in lysates prepared from cells activated by antibodymediated cross-linking of cell-surface immunoreceptors. THP-1 human acute monocytic leukemia cells were incubated with goat anti-Fcγ RIIA antibody (R&D Systems, Catalog # AF1875) or normal goat IgG (R&D Systems, Catalog # AB-108-C) followed by incubation with a donkey anti-goat IgG antibody (R&D Systems, Catalog # AF109) for 5 minutes [Maresco, D.L. et al. (1999) J. Immunol. 162:6458].
