(RUO)

Flow cytometric analysis of CD45.1 expression on mouse splenocytes. Splenic leucocytes from a C57BL/6 mouse (Left Panel) and SJL/J (Right Panel) mouse were separately preincubated with Purified Rat Anti-Mouse CD16/CD32 antibody (Mouse BD Fc Block™) (Cat. No. 553141/553142). The cells were then stained with either BD Horizon™ BV650 Mouse IgG2a, κ Isotype Control (Cat. No. 563417; dashed line histogram) or BD Horizon™ BV650 Mouse Anti-Mouse CD45.1 antibody (Cat. No. 563754; solid line histogram). Flow cytometric fluorescence histograms were derived from gated events based on forward and side light-scatter characteristics of viable splenocytes. Flow cytometric analysis was performed using a BD LSRFortessa™ Cell Analyzer System.

Preparation And Storage

Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze. The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated with BD Horizon™ BV650 under optimum conditions, and unconjugated antibody and free BD Horizon™ BV650 were removed.

Product Notices

Since applications vary, each investigator should titrate the reagent to obtain optimal results.
An isotype control should be used at the same concentration as the antibody of interest.
Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.

Antibody Details

A20

The A20 monoclonal antibody specifically binds to CD45 (Leukocyte Common Antigen) on all leukocytes of mouse strains expressing the CD45.1 alloantigen (eg, RIII, SJL/J, STS/A, DA). This alloantigen was originally named Ly-5.2, but was later changed to Ly-5.1 to conform with the convention that the .2 alloantigen designates the C57BL/6 strain. mAb A20 has been reported not to react with leukocytes of most other mouse strains which express the CD45.2 alloantigen. CD45 is a member of the Protein Tyrosine Phosphatase (PTP) family; its intracellular (COOH-terminal) region contains two PTP catalytic domains while the extracellular region is highly variable due to alternative splicing of exons 4, 5, and 6 (designated A, B, and C, respectively), and differing levels of glycosylation. CD45 isoforms in the mouse are cell type-, maturation-, and activation state-specific. The CD45 isoforms play complex roles in T-cell and B-cell antigen receptor signal transduction. The A20 antibody has been reported to inhibit some responses of B cells (from mice expressing the CD45.1 alloantigen) to antigens and LPS.

The antibody was conjugated to BD Horizon™ BV650 which is part of the BD Horizon™ Brilliant Violet™ family of dyes. This dye is a tandem fluorochrome of BD Horizon™ BV421 with an Ex Max of 405-nm and an acceptor dye with an Em Max at 650-nm. BD Horizon™ BV650 can be excited by the violet laser and detected in a filter used to detect APC-like dyes (eg, 660/20-nm filter). Due to the excitation and emission characteristics of the acceptor dye, there will be spillover into the APC and Alexa Fluor® 700 detectors. However, the spillover can be corrected through compensation as with any other dye combination.

Format Details

BV650

The BD Horizon Brilliant Violet™ 650 (BV650) Dye is part of the BD Horizon Brilliant Violet™ family of dyes. This tandem fluorochrome is comprised of a BV421 donor with an excitation maximum (Ex Max) of 406-nm and an acceptor dye with an emission maximum (Em Max) at 649-nm. BV650, driven by BD innovation, is designed to be excited by the violet laser (405-nm) and detected using an optical filter centered near 650-nm (e.g., a 660/20-nm bandpass filter). The acceptor dye can be excited by the Red (628–640-nm) laser resulting in cross-laser excitation and fluorescence spillover. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
