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 ≤ 0.5 µg per 106 cells in 100 µl volume. It is recommended that the reagent be titrated for optimal performance for each application.
Application Notes:
Additional reported applications (for the relevant formats) include: immunoprecipitation1, immunohistochemical staining1,2 of acetone-fixed frozen sections, and immunofluorescence microscopy3.

Description:
CD107a, also known as Lysosome-Associated Membrane Protein 1 (LAMP-1) or LGP-120, is a 110-140 kD type I membrane glycoprotein. The mature CD107a is heavily glycosylated from a 40 kD core protein. It is expressed by macrophages, epithelial cells, endothelial cells, and some tumor cells. This molecule is located on the luminal side of lysosomes and has been suggested to play a role in the protection of lysosome membrane from lysosomal hydrolases. CD107a is a ligand for galaptin. Upon activation, CD107a is transferred to the surface of cell membrane. It plays a role in cell adhesion and regulation of tumor metastasis, and mediates autoimmune disease progression.
