R&D Systems now offers two new Proteome Profiler Antibody Arrays, a Human Hematopoietic Soluble Receptor Array (Catalog # ARY011) and a Non-hematopoietic Soluble Receptor Array (Catalog # ARY012). The Hematopoietic and Non-hematopoietic Arrays provide a rapid, sensitive method to simultaneously detect changes in the levels of 105 and 119 soluble receptors, respectively. Proteome Profiler Antibody arrays require no specialized equipment and allow proteins of interest to be identified without having to perform multiple immunoprecipitation/Western blot experiments.

Multiple Proteins in Cell Culture Supernatants from Untreated and PMA-treated U937 Cells were Assessed using the Human Hematopoietic Soluble Receptor Antibody Array. A. The Proteome Profiler Human Hematopoietic Soluble Receptor Array (Catalog #ARY011) was used to simultaneously assess the relative levels of 105 analytes in cell culture supernatants from untreated or PMA-treated U937 human leukemic monocyte lymphoma cells. PC = Positive control. B. Histogram profiles for select proteins were generated by quantifying the mean spot pixel densities from the arrays using image software analysis.
