PerCP/Cy5.5 Anti-mouse CD45.1 Antibody
1153635 25 µg $95.00       
1153640 100 µg $270.00       
Clone: A20
Isotype: Mouse (A.SW) IgG2a, κ
Reactivity: Mouse
Immunogen: SJL mouse thymocytes and splenocytes
Formulation: Phosphate-buffered solution, pH 7.2, containing 0.09% sodium azide.
Preparation: The antibody was purified by affinity chromatography, and conjugated with PerCP/Cy5.5 under optimal conditions. The solution is free of unconjugated PerCP/Cy5.5 and unconjugated antibody.
Concentration: 0.2 mg/ml
Storage & Handling: The antibody solution should be stored undiluted between 2°C and 8°C, and protected from prolonged exposure to light. Do not freeze.
Application:

FC - Quality tested

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)), and immunofluorescence microscopy9.

Recommended Usage:

Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is ≤ 0.25 µg per 106 cells in 100 µl volume. It is recommended that the reagent be titrated for optimal performance for each application.

* PerCP/Cy5.5 has a maximum absorption of 482 nm and a maximum emission of 690 nm.

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.

Other Names: T200, Ly-5.1, LCA
Structure: Protein tyrosine phosphatase (PTP) family, 180-240 kD
Distribution: All hematopoietic cells except mature erythrocytes and platelets of the CD45.1 strain of mice
Function: Phosphatase, T and B cell activation
Ligand Receptor: Galectin-1, CD2, CD3, CD4
