Description
The 10D5 monoclonal antibody specifically recognizes Integrin alpha v beta 6 (αvβ6) that is also known as CD51/β6. This heterodimeric receptor is comprised of transmembrane type I alpha and beta chain glycoproteins that are encoded by ITGAV (integrin subunit alpha) and ITGB6 (integrin subunit beta 6), respectively. Like other integrins, αvβ6 serves as a transmembrane adhesion receptor that can tether the intracellular cytoskeleton to the extracellular matrix (ECM) by binding to R-G-D sequences of ECM protein ligands including fibronectin, vitronectin, and tenascin. Integrin αvβ6 likewise plays a key role in the activation of transforming growth factor beta-1 (TGFβ1) by its R-G-D-dependent release of TGFβ1 from regulatory Latency-associated peptide (LAP). Some viruses, such as. Coxsackieviruses and Herpes simplex virus-1 use Integrin αvβ6 as a receptor to infect cells. Integrin αvβ6 engages in bidirectional signaling, ie, outside-in and inside-out signaling, to regulate essential cellular functions. These include adhesion, migration, polarization, differentiation, and proliferation that are crucial to tissue homeostasis. Although not normally expressed on adult epithelial cells/keratinocytes, its expression is upregulated on these cells during the course of embryonic development, inflammation, tissue injury, wound healing, as well as malignant transformation. The 10D5 antibody blocks Integrin αvβ6-dependent cellular adhesion and migration and reportedly recognizes both human and mouse αvβ6 integrins. Binding of 10D5 antibody to αvβ6 is divalent-cation dependent.
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.
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 to the dye under optimum conditions that minimize unconjugated dye and antibody.

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.
5. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
6. 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.
7. When using high concentrations of antibody, background binding of this dye to erythroid fragments produced by ammonium chloride-based lysis, such as with BD Pharm Lyse™ Lysing Buffer (Cat. No. 555899), has been observed when the antibody conjugate was present during the lysis procedure. This may cause nonspecific staining of target cells, such as leukocytes, which have bound the resulting erythroid fragments. This background can be mitigated by any of the following: titrating the antibody conjugate to a lower concentration, fixing samples with formaldehyde, or removing erythrocytes before staining (eg, gradient centrifugation or pre-lysis with wash). This background has not been observed when cells were lysed with BD FACS™ Lysing Solution (Cat. No. 349202) after staining.

9. An isotype control should be used at the same concentration as the antibody of interest.

11. Please observe the following precautions: We recommend that special precautions be taken (such as wrapping vials, tubes, or racks in aluminum foil) to protect exposure of conjugated reagents, including cells stained with those reagents, to any room illumination. Absorption of visible light can significantly affect the emission spectra and quantum yield of tandem fluorochrome conjugates.
12. Tandem fluorochromes contain both an energy donor and an energy acceptor. Although every effort is made to minimize the lot-to-lot variation in the efficiency of the fluorochrome energy transfer, differences in the residual emission from the donor may be observed. Additionally, multi-laser cytometers may directly excite both the donor and acceptor fluorochromes. Therefore, we recommend for every tandem conjugate, a matched individual single-stain control be acquired for generating a compensation or spectral unmixing matrix.
13. Human donor specific background has been observed in relation to the presence of anti-polyethylene glycol (PEG) antibodies, developed as a result of certain vaccines containing PEG, including some COVID-19 vaccines. We recommend use of BD Horizon Brilliant™ Stain Buffer in your experiments to help mitigate potential background.
