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.
Product Notices
- Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
- 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).
- 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.
- This APC-conjugated reagent can be used in any flow cytometer equipped with a dye, HeNe, or red diode laser.
- Source of all serum proteins is from USDA inspected abattoirs located in the United States.
- For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.

Companion Products
The TS2/7 monoclonal antibody specifically recognizes Integrin alpha 1 (Integrin α1) which is also known as CD49a (CD49 antigen-like family member A) and Very late antigen 1α subunit (VLA-1). Integrin α1 (CD49a) is an ~200 kDa single pass type I transmembrane glycoprotein that is encoded by ITGA1 (Integrin subunit alpha 1) which belongs to the Integrin alpha chain family. Integrin α1 (CD49a) associates with the integrin β1 chain (CD29) to form the Integrin α1β1 heterodimer (also known as CD49a/CD29 or the VLA-1 complex) that serves as a receptor for collagen and laminin-1. It is expressed on activated T cells, monocytes, neuronal cells, and smooth muscle cells. Integrin α1 (CD49a) reportedly plays a role in leucocyte migration into tissues and can costimulate T cell proliferation and cytokine production. It is also involved in cellular attachment during the development of both the central and peripheral nervous systems.
