Preparation And Storage
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 CompBead to ensure that BD CompBeads are appropriate for your specific cellular application.
Product Notices
- Researchers should determine the optimal concentration of this reagent for their individual applications.
- 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.
- 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.

The V7.1 monoclonal antibody specifically recognizes CD101 which is also known as P126 or Glu-Trp-Ile EWI motif-containing protein 101 (EWI-101). CD101 is encoded by IGSF2 (Immunoglobulin superfamily member 2) and belongs to the EWI (sharing a conserved glutamine-tryptophan-isoleucine motif) family within the Ig superfamily. CD101 is a ~135-140 kDa type I transmembrane glycoprotein that has a short cytoplasmic domain with potential phosphorylation sites and an extracellular region with seven immunoglobulin-variable (IgV)-like domains. CD101 is expressed as homodimers by granulocytes, monocytes, dendritic cells, and some T cells. Its expression by T cells may be upregulated upon activation through the CD3 complex. CD101 may play a role in TCR/CD3-dependent T-cell activation.
The antibody was conjugated to BD Horizon Red 718, which has been developed exclusively for BD Biosciences as a better alternative to Alexa Fluor® 700. BD Horizon Red 718 can be excited by the red laser (628 – 640 nm) and, with an Em Max around 718 nm, it can be detected using a 730/45 nm filter. Due to similar excitation and emission properties, we do not recommend using R718 in combination with APC-R700 or Alexa Fluor® 700.
