BV421 Mouse Anti-Human OX40 Ligand (CD252)
BV421 Mouse Anti-Human OX40 Ligand (CD252)
Flow cytometric analysis of OX40 Ligand expression on human peripheral blood lymphocytes. Human peripheral blood mononuclear cells were preincubated with recombinant OX40 Ligand and stimulated with phytohemagglutinin (PHA; Sigma L-1668) for 3 days. The cells were then stained with either BD Horizon™ BV421 Mouse IgG1, k Isotype Control (Cat. No. 562438; dashed line histogram) or BD Horizon™ BV421 Mouse Anti-Human OX40 Ligand (CD252) (Cat. No. 563766; solid line histogram). The fluorescence histograms were derived from gated events with the forward and side light-scatter characteristics of viable lymphocytes. Flow cytometric analysis 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 monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated with BD Horizon BV421 under optimum conditions, and unconjugated antibody and free BD Horizon BV421 were removed.

Recommended Assay Procedures

For optimal and reproducible results, BD Horizon Brilliant Stain Buffer should be used anytime two or more BD Horizon Brilliant dyes are used in the same experiment.  Fluorescent dye interactions may cause staining artifacts which may affect data interpretation.  The BD Horizon Brilliant Stain Buffer was designed to minimize these interactions.  More information can be found in the Technical Data Sheet of the BD Horizon Brilliant Stain Buffer (Cat. No. 563794/566349).

Product Notices

  1. This reagent has been pre-diluted for use at the recommended Volume per Test. We typically use 1 × 10^6 cells in a 100-µl experimental sample (a test).
  2. An isotype control should be used at the same concentration as the antibody of interest.
  3. Source of all serum proteins is from USDA inspected abattoirs located in the United States.
  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.

ik-1

The ik-1 monoclonal antibody specifically binds to OX40 Ligand (OX40L) which is also known as CD252 and CD134 Ligand. OX40L is encoded by TNFSF4 (Tumor necrosis factor (ligand) superfamily, member 4). OX40L a 34 kDa type II transmembrane glycoprotein that is expressed by dendritic cells, B cells, human umbilical vein endothelial cells (HUVEC) and other types of vascular endothelial cells. OX40L serves as a costimulatory ligand by binding to and signaling through OX40 (CD134) which is expressed on activated T cells. It also mediates adhesion of activated T cells or OX40-positive transformed cells to vascular endothelial cells. Monocyte-derived dendritic cells (MoDC) express OX40 Ligand after stimulation through CD40. Ligation of OX40 Ligand expressed by activated MoDC can significantly increase their cytokine production.

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.
