Description

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
Flexi-Fluors™ are provided at a standard 0.2 mg/mL concentration. We recommend titrating this reagent to determine the optimal concentration for each application. For many flow cytometry applications, conjugated antibodies perform well at concentrations ranging from 0.03 to 1.0 µg per million cells in 100 µL. We recommend testing a range of concentrations starting from 10 µg/mL.

For example, make five 1:1 serial dilutions of the 0.2 mg/mL antibody. Add 5 µL of each dilution (including the undiluted antibody) to 100 µL of cells (at 107 cells/mL) to test six concentrations -- 1.0, 0.5, 0.25, 0.125, 0.06, and 0.03 µg per million cells in 100 µL volume. Compare staining patterns or create a titration curve using the MFI or staining index to determine the optimal concentration.
Excitation Laser
Red Laser (633 nm)
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)).
