Profile: Hypromatrix, Inc. offers signal transduction antibody array, apoptosis antibody array, cellcycle antibody array, custom antibody array, primary antibodies, and labeled antibodies. We offer services that include protein-protein interaction screening, gene cloning, gene expression, and protein purification. Each of our signal transduction antibody array contains 400 high quality antibodies against well-studied signaling proteins, and they are arrayed onto a nitrocellulose membrane with a proprietary technique to completely retain the biological activities such as the binding of respective antigens. Our cell cycle antibody arrays are generally used to screen novel protein-protein interactions that regulate cell cycle, to find out changes in protein-protein interactions during cell cycle, and to examine changes in protein phosphorylations during cell cycle phases.
