Lyse/Fix Buffer

Catalog No. ABIN1379873

Product Details

Application: Intracellular Flow Cytometry (ICFC)

Brand: BD Phosflow™

Characteristics: BD Phosflow™ Lyse/Fix Buffer is intended to be used for the lysing and fixing of whole blood for use with intracellular flow cytometry. For example, after cell stimulation with kinase activators, such as phorbol esters, the BD Phosflow™ Lyse/Fix buffer can be used for lysing red blood cells and for fixing leukocytes in one step. This allows investigators to rapidly inactivate kinases, phosphatases and/or proteases, so that the in vivo phosphorylation state of the cell can be examined. The BD Phosflow™ Lyse/Fix Buffer has been reported to preserve the light scattering properties of the cell and may be used on human and mouse whole blood. Whole blood lysis has been shown to be as effective as density gradient centrifugation in the preparation of PBMCs for lymphocyte subset analysis. In many cases, phospho-specific antibodies may be used simultaneously with the staining of cell surface markers (e.g CD markers). Not all cell surface markers, however, are compatible with the BD Phosflow™ Lyse/Fix Buffer.
