特異性:This item is specific for the extracellular domain of the human PDGF receptor beta subunit. This was confirmed in binding studies using several different cell lines and by its ability to immunoprecipitate PDGF receptor beta complexed with 125I-PDGF-BB. This item does not recognize PDGF receptor alpha. PDGF receptor beta is a member of the class III receptor tyrosine kinase family that also includes M-CSF receptor, SCF receptor and Flt-3. Binding of PDGF-BB induces receptor homodimerization or heterodimerization with PDGF receptor alpha.
