Biolegend, 110745, Purified anti-mouse CD45.1 (Maxpar® Ready) Antibody, 100μg

CD45.1 is an alloantigen of CD45, expressed by Ly5.1 bearing mouse strains (e.g., RIII, SJL/J, STS/A, DA). CD45, a member of the protein tyrosine phosphatase (PTP) family, is a 180-240 kD glycoprotein expressed on all hematopoietic cells except mature erythrocytes and platelets. There are multiple isoforms in mice that play key roles in TCR and BCR signal transduction. These isoforms are very specific to the activation and maturation states of the cell as well as specific cell types. The primary ligands for CD45 are galectin-1, CD2, CD3, CD4, TCR, CD22, and Thy-1.

Recommended Usage: This product is suitable for use with the Maxpar® Metal Labeling Kits. For metal labeling using Maxpar® Ready antibodies, proceed directly to the step to Partially Reduce the Antibody by adding 100 µl of Maxpar® Ready antibody to 100 µl of 4 mM TCEP-R in a 50 kDa filter and continue with the protocol. Always refer to the latest version of Maxpar® User Guide when conjugating Maxpar® Ready antibodies.
Application Notes: The A20 antibody does not react with leukocytes or mouse cells expressing the CD45.2 alloantigen. Additional reported applications (for relevant formats of this clone) include: immunoprecipitation3, in vitro blocking of B cell responses1,2, immunohistochemical staining of frozen sections: OCT embedded7 and acetone-fixed4-6 (direct immunofluorescence detection with fluorochrome conjugated A20 was used in (5) and (6)).

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.
