C57BL/6 mouse frozen lymph node section was fixed with 4% paraformaldehyde (PFA) for 10 minutes at room temperature and blocked with 5% FBS plus 5% rat serum for 1 hour at room temperature. Then the section was stained with 2.5 µg/mL of B220 (clone RA3-6B2) Alexa Fluor® 594 (red), 2.5 µg/mL of CD4 (clone RM4-5) Alexa Fluor® 488 (green), and 2.5 µg/mL of CD8 (clone 53-6.7) Alexa Fluor® 647 (blue) overnight at 4°C. The image was captured by 10X objective.

    Paraformaldehyde-fixed (4%), 500 μm-thick mouse spleen section was processed according to the Ce3DTM Tissue Clearing Kit protocol (Cat. No. 427701). The section was costained with anti-mouse CD3ε Antibody (clone 500A2) Alexa Fluor® 488 at 5 µg/mL (green), and anti-mouse/human CD45R/B220 Antibody (clone RA3-6B2) Alexa Fluor® 594 at 5 µg/mL (magenta) and counterstained with DAPI (blue). The section was then optically cleared and mounted in a sample chamber. The image was captured with a 10X objective using Zeiss 780 confocal microscope and processed by Imaris image analysis software.

Description

CD45R, also known as B220, is an isoform of CD45. It is a member of the protein tyrosine phosphatase (PTP) family with a molecular weight of approximately 180-240 kD. CD45R is expressed on B cells (at all developmental stages from pro-B cells through mature B cells), activated B cells, and subsets of T and NK cells. CD45R (B220) is also expressed on a subset of abnormal T cells involved in the pathogenesis of systemic autoimmunity in MRL-Faslpr and MRL-Fasgld mice. It plays a critical role in TCR and BCR signaling. The primary ligands for CD45 are galectin-1, CD2, CD3, and CD4. CD45R is commonly used as a pan-B cell marker; however, CD19 may be more appropriate for B cell specificity.

Recommended Usage

Each lot of this antibody is quality control tested by immunofluorescence staining. For immunohistochemistry, a concentration range of 2.5-5 μg/mL is recommended. For immunofluorescence microscopy, a concentration range of 1.25 - 10 μg/mL is recommended. For flow cytometric staining, the suggested use of this reagent is ≤0.25 µg per million cells in 100 µL volume. For 3D immunohistochemistry on formalin-fixed tissues, a concentration of 5.0 µg/mL is suggested. It is recommended that the reagent be titrated for optimal performance for each application.

* Alexa Fluor® 594 has an excitation maximum of 590 nm, and a maximum emission of 617 nm.

Application Notes

Clone RA3-6B2 has been described to react with an epitope on the extracellular domain of the transmembrane CD45 glycoprotein which is dependent upon the expression of exon A and specific carbohydrate residues. Additional reported applications (for the relevant formats) include: immunoprecipitation1, in vitro and in vivo modulation of B cell responses2-4, immunohistochemistry of acetone-fixed frozen sections and formalin-fixed paraffin-embedded sections5,6, and spatial biology (IBEX)14,15.
