Beschreibung: CD45RB is an isoform of CD45 with exon 5 splicing (encodes B determinant). It is a 220 kD glycoprotein expressed on peripheral B cells, naïve T cells, thymocytes, weakly on macrophages, and dendritic cells. It plays a critical role in TCR and BCR signaling. As T cells become activated and progress from naïve to memory cells, CD45RB expression is downregulated. Additionally, functionally distinct CD4 T cell subsets, which secrete differing cytokine profiles, can be separated by CD45RB intensity. The primary ligands for CD45 are galectin-1, CD2, CD3, CD4 and Thy-1. Distribution: Peripheral B cells, naïve T cells, most thymocytes, low density on macrophages and dendritic cells Function: Phosphatase, T cell development and activation Structure: Phosphatase receptor (CD45 gene exon 5), 220 kD

Anwendungen

Applikationshinweise: Additional reported applications (for the relevant formats) include: immunoprecipitation, immunohistochemistry of acetone-fixed frozen sections and formalin-fixed paraffin-embedded sections. Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For immunofluorescent staining, the suggested use of this reagent is < 0.25 µg per 10 cells in 100 µl volume. It is recommended that the reagent be titrated for optimal performance for each application.

Reinigung: The antibody was purified by affinity chromatography, and conjugated with PE under optimal conditions. The solution is free of unconjugated PE and unconjugated antibody.

Buffer: Phosphate-buffered solution, pH 7.2, containing 0.09% sodium azide.

Lagerung: The antibody solution should be stored undiluted at 4°C and protected from prolonged exposure to light. Do not freeze.

Forschungsgebiet: CD Antigene

Beschränkungen: Nur für Forschungszwecke einsetzbar
