Description | Specificity: Mouse CD49b, Mr 160-kDa. The monoclonal antibody DX5 reacts with CD49b, also known as very late antigen-2 (VLA-2) and alpha 2 integrin.1 The antibody stains the majority of NK cells and a small subpopulation of T cells in all mouse strains tested (e.g., A/J, AKR, BALB/c, C3H/HeJ, C57BL/6, C57BL/10, C57BR, C58, CBA/Ca, CBA/J, DBA/1, DBA/2, SJL, SWR).2. 3 Three-color flow cytometry analysis has revealed that most cells that express NK-1.1 (NKR-P1C) also express CD49b. However, small subsets of DX5+NK-1.1- and DX5-NK- 1.1+ cells can be found, especially among the CD3+ population of T lymphocytes.2 NK cells cultured in the presence of IL-2 progressively lose reactivity with DX5 as a consequence of cellular proliferation.1 Therefore |
