BV421 Mouse Anti-Human TCR Vβ5.1
BV421 Mouse Anti-Human TCR Vβ5.1
Two-color flow cytometric analysis of TCR Vβ5.1 expression on Human peripheral blood T lymphocytes. Human peripheral blood cells were stained with APC Mouse Anti-Human CD3 antibody (Cat. No. 561811/555335/561810) and with either BD Horizon™ BV421 Mouse IgG1, κ Isotype Control (Cat. No. 562438; Left Panel) or BD OptiBuild™ BV421 Mouse Anti-Human TCR Vβ5.1 antibody (Cat. No. 751801; Right Panel). Erythrocytes were lysed with BD Pharm Lyse™ Lysing Buffer (Cat. No. 555899). The bivariate pseudocolor density plot showing the correlated expression of TCR Vβ5.1 (or Ig Isotype control staining) versus CD3 was derived from gated events with the forward and side light-scatter characteristics of viable lymphocytes. Flow cytometric analysis was performed using a BD LSRFortessa™ X-20 Flow Cytometer 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 that minimize unconjugated dye and antibody.

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).

Product Notices

  1. The production process underwent stringent testing and validation to assure that it generates a high-quality conjugate with consistent performance and specific binding activity. However, verification testing has not been performed on all conjugate lots.
  2. Researchers should determine the optimal concentration of this reagent for their individual applications.
  3. An isotype control should be used at the same concentration as the antibody of interest.
  4. 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.

LC4

The LC4 monoclonal antibody specifically recognizes the human variable beta 5.1 (Vβ5.1) domain of the beta subunit for the αβ T cell receptor for antigen (TCR αβ). TCR Vβ5.1 is encoded by TRBV5-1 (T cell receptor beta variable 5-1), one of five functional genes within the TRBV5 subgroup in the T cell receptor beta (TRB) locus. The heterodimeric TCR αβ is composed of two disulfide-linked transmembrane glycoproteins, ie, highly variable TCRα and TCRβ chains. These chains are each comprised of an extracellular N-terminal variable (V) region domain followed by a constant (C) region domain, a transmembrane region, and a short C-terminal cytoplasmic tail. The TCR Vβ repertoire is known to be extensive due to the many different combinations of TCR gene segments (, , and ) as well as junctional region diversity. TCR Vβ5.1 is variably expressed on subsets of TCR αβ-positive thymocytes and peripheral CD4+ or CD8+ T cells. In association with the CD3 complex of signaling proteins, the TCR αβ recognizes peptide-major histocompatibility complexes (pMHC) that are displayed on other cells to mediate cellular responses. The LC4 antibody is useful for analyzing the levels of TCR Vβ5.1 expressed by individual cells as well as the numbers or frequencies of TCR Vβ5.1-positive cells within test samples. The LC4 antibody can be used to help characterize the TCR Vβ repertoires of T cell populations during health as well as in response to vaccination, infectious disease, aging, transplantation, autoimmunity or cancer.

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.
