MaxLight(TM)550 is a new Yellow-Green photostable dye conjugate comparable to Alexa Fluor(TM)546, 555, DyLight(TM)549 , Cy3(TM), TRITC and offers better labeling efficiency, brighter imaging and increased immunodetection. Absorbance (550nm), Emission (575nm), Extinction Coefficient 150,000. Human CD221 is a 155kD receptor tyrosine kinase, also known as Insulin-like growth factor I receptor (IGF-I Receptor). CD221 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. Applications: Suitable for use in Flow Cytometry, Western Blot and Immunohistochemistry. Other applications have not been tested. Recommended Dilutions: Flow Cytometry: 1:10.
