靶点与抗体说明

The RM134L antibody reacts with CD252 (OX-40 Ligand, OX-40L), a member of the NGF/TNF superfamily which is present on antigen-presenting cells and activated B lymphocytes. OX-40L interacts with OX-40 Antigen (CD134) found predominantly on activated T cells. This ligand-receptor pair is grouped with pairs such as CD40-CD40L and CD80- or CD86-CD28, which contribute significantly to B-cell/T-cell interaction during the immune response. The OX-40L-OX-40 interaction is reciprocally costimulatory in that both T cells and B cells are activated in cross-linking. Stimulation via OX-40 Antigen increases the proliferative and IL-2 production responses of activated T cells, while stimulation via OX-40L enhances proliferation and Ig secretion by activated B cells. The RM134L mAb stains B cells activated for four days with anti-IgM plus anti-CD40 (Clone HM40-3) antibodies. An increased binding of OX-40-Ig fusion protein to mouse splenic B cells was observed when B cells were treated with lipopolysaccharide (LPS), suggesting that OX-40L expression is augmented in LPS-activated splenic B cells when compared to resting cells, but this observation could not be confirmed with the RM134L mAb. In addition, other studies with OX-40-Ig fusion protein detected OX-40L on CD4+ and CD8+ activated splenic T

核心参数

荧光染料信息

BB515 The BD Horizon Brilliant™ Blue 515 (BB515) dye is part of the BD Horizon Brilliant™ Blue family of dyes. This dye is a polymer fluorochrome with an excitation maximum (Ex Max) at 490-nm and an emission maximum (Em Max) of 515-nm. Driven by BD innovation, BB515 is designed to be excited by the blue laser (488-nm) and detected using an optical filter centered near 520-nm (e.g., 530/30-nm). BB515 reagents are significantly brighter than equivalent FITC or Alexa Fluor™ 488 reagents with less spillover into the PE detector. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye. 格式:BB515最多激发源:490 nm最多发射源:515 nm
