NEW RECOMBINANT HUMAN PROTEINS
More recombinant human protein products from ChemoTactics, Inc. are now available at reduced prices! These include CCL2 (MCP-1), CCL3 (MIP-1α), CCL7 (MCP-3), CCL19 (MIP-3β), and CXCL8 (IL-8). Also, new biotinylated versions of CXCL12a biotin (SDF-1α) and CCL7 biotin (MCP-3) have just been added to this product line! These biotinylated proteins are made using an enzymatic method which has several advantages over chemical biotinylation methods. The attachment of biotin at a specific lysine residue within the C-terminal avi tag sequence is nearly 100% complete, and leads to modified chemokines with functionalities comparable to those of the unmodified chemokines. Combining these proteins with avidin analogues conjugated to various fluorescent labels, biotinylated chemokines are useful in studies on receptor identification, distribution, chemokine binding, and other cellular assays. They serve as great tools in visualization and quantification, and replace the need for radioactively labeled chemokines. Check back often for more new products from ChemoTactics, Inc.!
QED introduces 4 new antibodies that target leukemia and lymphoma markers: MLL, ENL, AF4, and HGAL. These antibodies are thoroughly characterized and are ideal reagents for studying oncogene expression and regulation.
Evaluating pharmacokinetics or tissue distribution of therapeutic antibodies requires methods that distinguish an administered therapeutic antibody from endogenous immunoglobulins in patient samples. (learn more)
