描述:
The LG.3A10 monoclonal antibody specifically binds to CD27, a lymphocyte-restricted member of the Tumor Necrosis Factor Receptor
family which binds to CD70. The CD27 molecule is a 45-kDa transmembrane glycoprotein which is constitutively expressed by lymphocytes
of the T lineage: virtually all thymocytes and over 90% of peripheral T cells bearing both
αβ and γδ
T-cell receptors. CD27 cooperates with
the pre-TCR in mediating thymocyte differentiation and expansion. In addition, one to ten percent of mature peripheral B cells express CD27,
and CD27’s role in the differentiation of human plasma cells has been studied. Mouse NK cells, freshly isolated and IL-2-activated, also
express CD27. In the bone marrow, CD27 is found on a progenitor population which provides short-term hematopoietic reconstitution. Cells
of the myeloid lineage do not express CD27. Cross-linked LG.3A10 mAb has been reported to amplify the proliferative response of purified T
lymphocytes to suboptimal mitogenic stimulation1 and to enhance NK-cell proliferation and IFN-γ
production. In contrast, non-cross-linked
LG.3A10 mAb inhibits CD3-induced pre-T cell development by interfering with the receptor-ligand interaction. This hamster mAb to a mouse
leukocyte antigen has been observed to cross-react with a similar population of rat leukocytes.
The antibody was conjugated to BD Horizon™ BV510 which is part of the BD Horizon™ Brilliant Violet™ family of dyes. With an Ex Max
of 405-nm and Em Max at 510-nm, BD Horizon™ BV510 can be excited by the violet laser and detected in the BD Horizon™ V500
(525/50-nm) filter set. BD Horizon™ BV510 conjugates are useful for the detection of dim markers off the violet laser.
