BV421 Mouse Anti-Human CD235a
BV421 Mouse Anti-Human CD235a
Flow cytometric analysis of CD235a expression on human peripheral blood erythrocytes. Whole blood was stained with BD Horizon™ BV421 Mouse anti-Human CD235a antibody (Cat. No. 562938; solid line histogram) or with a BD Horizon™ BV421 Mouse IgG2b, κ Isotype Control (Cat. No. 562748; dashed line histogram). The fluorescence histograms were derived from gated events with the forward and side light-scatter characteristics of erythrocytes. Flow cytometry was performed using a BD™ LSR II Flow Cytometer System.

Preparation And Storage

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

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).

GA-R2 (HIR2)

The GA-R2 (also known as HIR2) monoclonal antibody specifically binds to CD235a and CD235b. CD235a is also known as Glycophorin A (GYPA, GPA, GLPA), Sialoglycoprotein alpha, MN sialoglycoprotein, or PAS-2. CD235b is otherwise known as Glycophorin B (GYPB, GPB, GLPB), Sialoglycoprotein delta, SS-active sialoglycoprotein, or PAS-3. CD235a and CD235b are type I transmembrane sialoglycoproteins that are expressed on human erythrocytes, erythroid precursor cells and certain leukemic cell types. CD235a carries blood group M and N antigens, whereas CD235b contains S, s, and U antigens. This antibody is useful for the identification and characterization of erythrocytes, certain myeloid leukemic cell types, and studies of erythroid cell development and infectious diseases with erythrocyte involvement. Glycophorins may play a role in preventing cell agglutination.

The antibody was conjugated to BD Horizon™ BV421 which is part of the BD Horizon™ Brilliant Violet™ family of dyes.  With an Ex Max of 407-nm and Em Max at 421-nm, BD Horizon™ BV421  can be excited by the violet laser and detected in the standard Pacific Blue™ filter set (eg, 450/50-nm filter). BD Horizon™ BV421  conjugates are very bright, often exhibiting a 10 fold improvement in brightness compared to Pacific Blue™ conjugates.

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.
