Biolegend, 338811, Purified anti-human CD44 (Maxpar® Ready) Antibody, 100μg

CD44 is a 80-95 kD glycoprotein also known as Hermes, Pgp1, H-CAM, or HUTCH. It is expressed on all leukocytes, endothelial cells, hepatocytes, and mesenchymal cells. As B and T cells become activated or progress to the memory stage, CD44 expression increases from a low or mid level of intensity to high expression levels. Thus, CD44 has been reported to be a valuable marker for memory cell subsets. CD44 is an adhesion molecule involved in leukocyte attachment to and rolling on endothelial cells, homing to peripheral lymphoid organs and to the sites of inflammation, and leukocyte aggregation.

Q: Can I obtain CyTOF data related to your Maxpar® Ready antibody clones?
A: We do not test our antibodies by mass cytometry or on a CyTOF machine in-house. The data displayed on our website is provided by Fluidigm®. Please contact Fluidigm® directly for additional data and further details.

Q: Can I use Maxpar® Ready format clones for flow cytometry staining?
A: We have not tested the Maxpar® Ready antibodies formulated in solution containing EDTA for flow cytometry staining. While it is likely that this will work in majority of the situations, it is best to use the non-EDTA formulated version of the same clone for flow cytometry testing. The presence of EDTA in some situations might negatively affect staining.
Q: I am having difficulty observing a signal after conjugating a metal tag to your Maxpar® antibody. Please help troubleshoot.
A: We only supply the antibody and not test that in house. Please contact Fluidigm® directly for troubleshooting advice: http://techsupport.fluidigm.com/
Q: Is there a difference between buffer formulations related to Maxpar® Ready and purified format antibodies?
A: The Maxpar® Ready format antibody clones are formulated in Phosphate-buffered solution, pH 7.2, containing 0.09% sodium azide and EDTA. The regular purified format clones are formulated in solution that does not contain any EDTA. Both formulations are however without any extra carrier proteins.
