General description

Lyso bis-phosphatidic acid (LBPA, Lysobisphosphatidic acid, L(bis)PA) is a lipid that is exclusively located in late endosomes and is used as a late endosome marker. One of the characteristic features of late endosomes is a complex system of internal membranes within the lumen that contains large amounts of the unique, poorly degradable LBPA, and thus forms a specialized membrane domain within endosomes. Late endosomes function not only as a major protein-sorting compartment, but also an obligatory station for LDL and other endocytosed ligands destined for degradation. Research shows that the LBPA-rich membranes within late endosomes regulate cholesterol transport, presumably by acting as a collection and distribution device. The genetic disease Niemann–Pick type C (NPC) is characterized by both lysosomal and endosomal storage disorders. In skin fibroblasts from NPC patients, cholesterol accumulation is seen within vesicles containing late endosome markers LBPA and Rab7.

Specificity

Clone 6C4 specifically detects LBPA, but not PC, PE, SM, PS, CL, PI, Sul, Chol, Cer, or CE purified from baby hamster kidney (BHK) cell lipid extract (Kobayahsi, T., et al. (1998). Nature. 392(6672):193-197).
Target molecule is not species-specific.

Immunogen

Endosomal membranes from baby hamster kidney fibroblasts (BHK) corresponding to Hamster LBPA.

Application

Immunocytochemistry Analysis: 4.0 µg/mL from a representative lot detected LBPA in A431, HUVEC and NIH/3T3 cells.
Immunocytochemistry Analysis: A representative lot detected late endosome LBPA immunoreactivity by fluorescent immunocytochemistry using MLN64-overexpressing MCF7 cells (Alpy, F., et al. (2001). J Biol Chem. 276(6):4261-4269).
Immunocytochemistry Analysis: A representative lot detected late endosome LBPA immunoreactivity in skin fibroblasts from healthy donors, as well as Niemann–Pick type C (NPC) and Tay-Sachs disease patients by fluorescent immunocytochemistry (Kobayahsi, T., et al. (1999). Nat Cell Biol. 1(2):113-118).
Immunocytochemistry Analysis: A representative lot detected late endosome LBPA immunoreactivity in baby hamster kidney (BHK) cells by fluorescent immunocytochemistry (Kobayahsi, T., et al. (1998). Nature. 392(6672):193-197).
Electron Microscopy Analysis: A representative lot detected similar cellular LBPA distribution in the skin fibroblasts from autosomal recessive Niemann–Pick type C disease (NPC) patients as seen in baby hamster kidney (BHK) cells (Kobayahsi, T., et al. (1999). Nat Cell Biol. 1(2):113-118).
Electron Microscopy Analysis: A representative lot detected LBPA immunoreactivity specifically associated with the late endosomes in baby hamster kidney (BHK) cells, but not the lgp120-positive limiting membranes of the same endosomes (Kobayahsi, T., et al. (1998). Nature. 392(6672):193-197).
ELISA Analysis: A representative lot specifically detected wells coated with total baby hamster kidney (BHK) cell lipid extract or purified LBPA, but not other lipids (PC, PE, SM, PS, CL, or PI) purified BHK lipid extract (Kobayahsi, T., et al. (1998). Nature. 392(6672):193-197)
Dot Blot Analysis: A representative lot specifically detected purified LBPA spotted on a HPTLC plate, but not other lipids (PC, PE, SM, PS, CL, PI, Sul, Chol, Cer, CE) purified from baby hamster kidney (BHK) cell lipid extract (Kobayahsi, T., et al. (1998). Nature. 392(6672):193-197).
