BV421 Rat Anti-Mouse CD45
BV421 Rat Anti-Mouse CD45

Flow cytometric analysis of CD45 expression on mouse splenocytes. Splenic leucocytes from BALB/c mice were preincubated with Purified Rat Anti-Mouse CD16/CD32 antibody (Mouse BD Fc Block™) (Cat. No. 553141/553142). The cells were stained with either BD Horizon™ BV421 Rat IgG2b, κ Isotype Control (Cat No. 562603; dashed line histogram) or BD Horizon™ BV421 Rat Anti-Mouse CD45 antibody (Cat No. 567799; solid line histogram) at 0.5 µg/test. BD Via-Probe™ Cell Viability 7-AAD Solution (Cat. No. 555815/555816) was added to cells right before analysis. The fluorescence histogram showing CD45 expression (or Ig Isotype control staining) was derived from gated events with the forward and side light-scatter characteristics of viable (7-AAD-negative) mouse leucocytes. Flow cytometry and data analysis were performed using a BD LSRFortessa™ Cell Analyzer System and FlowJo™ software. Data shown on this Technical Data Sheet are not lot specific.

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 to the dye under optimum conditions and unconjugated antibody and free dye were removed.

Recommended Assay Procedures

BD® CompBeads can be used as surrogates to assess fluorescence spillover (Compensation). When fluorochrome conjugated antibodies are bound to BD® CompBeads, they have spectral properties very similar to cells.  However, for some fluorochromes there can be small differences in spectral emissions compared to cells, resulting in spillover values that differ when compared to biological controls. It is strongly recommended that when using a reagent for the first time, users compare the spillover on cells and BD® CompBeads to ensure that BD® CompBeads are appropriate for your specific cellular application.

For optimal and reproducible results, BD Horizon Brilliant™ Stain Buffer should be used anytime BD Horizon Brilliant™ dyes are used in a multicolor flow cytometry panel. Fluorescent dye interactions may cause staining artifacts which may affect data interpretation. The BD Horizon Brilliant™ Stain Buffer was designed to minimize these interactions. When BD Horizon Brilliant™ Stain Buffer is used in in the multicolor panel, it should also be used in the corresponding compensation controls for all dyes to achieve the most accurate compensation. For the most accurate compensation, compensation controls created with either cells or beads should be exposed to BD Horizon Brilliant™ Stain Buffer for the same length of time as the corresponding multicolor panel. More information can be found in the Technical Data Sheet of the BD Horizon Brilliant™ Stain Buffer (Cat. No. 563794/566349) or the BD Horizon Brilliant™ Stain Buffer Plus (Cat. No. 566385).

I3/2.3

The mAb I3/2.3 recognizes mouse CD45, which is also known as the leukocyte common antigen (L-CA or LCA), T200, or Lymphocyte antigen 5 (Ly-5). CD45 is a 180-240 kDa single-pass type I transmembrane glycoprotein that is encoded by Ptprc (protein tyrosine phosphatase, receptor type, C) which belongs to the protein tyrosine phosphatase (PTP) family. CD45 is variably expressed on thymocytes and other hematopoietic cells except mature erythrocytes and platelets. Different isoforms of CD45 arise from alternative splicing of variable exons 4, 5, and 6, which encode A, B, and C determinants, respectively, that encode extracellular domains of the transmembrane receptor. The differential expression of these isoforms is related to the cell's lineage as well as its state of activation and maturation. The mAb I3/2.3 reportedly recognizes all CD45 isoforms. CD45 plays key roles as a protein tyrosine-protein phosphatase in leucocyte responses including signal pathways transduced by antigen specific receptors expressed on T cells (TCRs) and B cells (BCRs).

The antibody was conjugated to BD Horizon™ BV421 which is part of the BD Horizon Brilliant™ Violet family of dyes. With an Ex Max near 407 nm and Em Max near 421 nm, BD Horizon™ BV421 can be excited by the violet laser (405 nm) and detected with a 450/50 nm filter. BD Horizon™ BV421 conjugates are very bright, often exhibiting a 10 fold improvement in brightness compared to Pacific Blue™ conjugates. Due to nearly identical excitation and emission properties but different spillover characteristics, BD Horizon™ BV421, Pacific Blue™, and BD Horizon™ V450 cannot be used simultaneously.

BV421
The BD Horizon Brilliant Violet™ 421 (BV421) Dye is part of the BD Horizon Brilliant Violet™ family of dyes. This polymer-technology based dye has an excitation maximum (Ex Max) of 407-nm and an emission maximum (Em Max) at 423-nm. Driven by BD innovation, BV421 is designed to be excited by the violet laser (405-nm) and detected using an optical filter centered near 420-nm (e.g., a 431/28-nm or 450/50-nm bandpass filter). BV421 is an ideal alternative for V450 as it is approximately ten times brighter with less spillover into the BV510/V500 detector. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
