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 CompBeads to ensure that BD® CompBeads are appropriate for your specific cellular application.
Product Notices
- Since applications vary, each investigator should titrate the reagent to obtain optimal results.
- 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).
- 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.
- Source of all serum proteins is from USDA inspected abattoirs located in the United States.

The Ber-ACT8 monoclonal antibody specifically binds to the human mucosal lymphocyte antigen 1 (HML-1). This is a 175 kDa type I transmembrane glycoprotein, also known as integrin αE (ITGAE, Integrin alpha-E) and CD103. It is found on >90% of intestinal intraepithelial lymphocytes (iIEL) associated with integrin β7. CD103 is also expressed on lamina propria T lymphocytes in the intestine and on phytohemagglutinin-stimulated peripheral blood lymphocytes. It is rarely expressed on resting peripheral blood lymphocytes. It has been suggested that CD103 may have an accessory function for activation of iIEL. CD103 has been reported as a useful tool in hairy cell leukemia research.
