Clone 1H7 recognizes an epitope in the alpha subunits of CD221, demonstrated by Western blotting, and is reported to partically block binding of IGF-I and IGF-II to CD221.
This product requires protein digestion pre-treatment of paraffin sections using trypsin or pronase. A suggested positive control for immunohistochemical applications is pancreas or placenta. For FACS analysis, use 10ul of the suggested working dilution to label 1x10^6 cells in 100ul.
This product is a low-endotoxin, preservative-free formulation. Endotoxin level is <0.01 EU/ug.
CD221, a 155kDa receptor tyrosine kinase also known as Insulin-like growth factor I receptor (IGF-I Receptor), is composed of two extracellular alpha-subunits and two transmembrane beta-subunits. CD221 is expressed in a range of tissues, including kidney, liver, placenta, mammary gland, brain, ovary and skin. The ligands for CD221 include IGF-I and IGF-II, which bind to CD221 and activate tyrosine kinase activity, resulting in phosphorylation of several intracellular signalling proteins.

Differential activation of a C/EBP beta isoform by a novel redox switch may confer the lipopolysaccharide-inducible expression of interleukin-6 gene.
MA1-81739 was used in chimmunoprecipitation to investigate the relationship between the transcriptional activities of different C/EBP beta isoforms and the regulation of interleukin 6 gene expression
