The L130 monoclonal antibody specifically binds to CD18 which is also known as β2 integrin. CD18 is an ~90-95 kDa type I transmembrane glycoprotein that is encoded by ITGB2. CD18 associates with the integrin α chains CD11a, CD11b, CD11c, or CD11d to form the LFA-1, Mac-1, p150,95, or αDβ2 heterodimers, respectively. CD18 is expressed on virtually all normal peripheral blood leucocytes. CD18 serves as a leucocyte adhesion receptor and signaling receptor. It is essential for many immune responses that require cell-to-cell contact, such as lymphocyte adhesion, natural killer (NK) cell and T-lymphocyte cytolysis, and T lymphocyte proliferation.
The antibody was conjugated to BD Horizon Red 718, which has been developed exclusively for BD Biosciences as a better alternative to Alexa Fluor® 700. BD Horizon Red 718 can be excited by the red laser (628 – 640 nm) and, with an Em Max around 718 nm, it can be detected using a 730/45 nm filter. Due to similar excitation and emission properties, we do not recommend using R718 in combination with APC-R700 or Alexa Fluor® 700.
