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 cell and BD® CompBeads to ensure that BD® CompBeads are appropriate for your specific cellular application.

Companion Products
The M-A261 monoclonal antibody specifically binds to CD26. CD26 is also known as dipeptidyl peptidase IV (DPPIV/DPP IV, DPP4) or adenosine deaminase binding protein (ADABP). CD26 is a 110 kDa type II transmembrane glycoprotein. CD26 is expressed by T lymphocytes and increases upon activation. It is also expressed by B cells, NK cells, and macrophages. CD26 is an ectoenzyme which plays an integral role in T-cell proliferation and may interact with extracellular matrix proteins such as fibronectin or collagen.
Fluorescein (FITC) is part of the BD blue family of dyes. This is a small organic fluorochrome with an excitation maximum (Ex Max) at 494-nm and an emission maximum (Em Max) at 518-nm. FITC is designed to be excited by the Blue laser (488-nm) and detected using an optical filter centered near 520 nm (e.g., a 530/30-nm bandpass filter). Please ensure that your instrument's configurations (lasers and optical filters) are appropriate for this dye.
The CD26 antigen can serve as a receptor for the coronavirus, MERS-CoV.
