Protein A (FITC)

Cannot supply to this region.

SKU:: GTX30958
Application:: Flow Cytometry, IF, ICC
Physical State:: Liquid
Storage Conditions:: 2-8[o]C
Supplier:: Genetex
Buffer:: 10mM Phosphate, 150mM NaCl, 1% BSA, 0.05% Sodium azide.
Species:: Bacteria
Extra Details:: Protein A (MW 42 kDa) is capable of binding to the Fc portion of immunoglobulins, especially IgGs, from a large number of species. One protein A molecule has been shown to bind at least 2 molecules of IgG simultaneously. The IgG binding domain of Protein A consists of three anti-parallel A Alpha-helicies, the third of which is disrupted when the protein is complexed with the Fc region of the immunoglobulins. Protein A will bind the Fc portion of human IgG subclasses, IgM, IgA and IgE; and mouse IgG1 (weakly), IgG2a, and IgG2b. Protein A also binds IgGs from other species, including monkey, rabbit, pig, guinea pig, dog, and cat. Fluorophore: Fluorescein isothiocyanate A max=492nm; E=520nm, Fluorophore/Protein: A492nm/A280nm=2.
