Application Notes:

Additional reported applications (for the relevant formats) include: immunoprecipitation1,2 and immunohistochemical staining3-5, 7-8 of acetone-fixed frozen sections.

Recommended Usage:

Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is ≤ 0.25 µg per 106 cells in 100 µl volume. It is recommended that the reagent be titrated for optimal performance for each application.

Ly-51 is a 140 kD protein also known as 6C3/BP-1. It is a homodimeric cell-surface glycoprotein with aminopeptidase A (APA) activity. Ly-51 is expressed on B cell progenitors, bone marrow stromal cell lines, thymic dendritic cells, and cortical epithelial cells. Ly-51 expression can be upregulated by IL-7 stimulation.

Other Names: 6C3/BP-1
Structure: Aminopeptidase A, 140 kD
Distribution: B progenitors, bone marrow stromal lines, thymic dendritic cells, cortical epithelial cells
Function: Aminopeptidase, may function in IL-7-driven proliferation of B cell precursors
