Anti-LBPA Antibody, clone 6C4 ZooMAb^® Mouse Monoclonal

Lyso(bis)phosphatidic acid (LBPA) is a structural isomer of phosphatidylglyerol with an atypical phospholipid stereo configuration. It is found in all animal tissues in a small amount ( 1%). However, it is only detected in late endosomes where it accounts for up to 17 mol % of total membrane phospholipids. It is abundant in the intralumenal vesicles that accumulate within late endosomes, accounting for the characteristic multi-vesicular appearance of these organelles. 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. LBPA is involved in the traffic of proteins and lipids that transit via late endosomes where membranes rich in LBPA regulate cholesterol transport and assist in presenting sphingolipids to their degradation enzymes. LBPA is shown to be highly resistant to lipases and phospholipases. Niemann Pick Type C (NPC) disease, caused by a mutation in either Niemann Pick C1 or C2 protein, results in lysosomal and endosomal disorders leading to excessive accumulation of cholesterol, particularly in skin fibroblasts. LBPA treatment of cells with NPC1 mutations is reported to compensate for the loss of NPC1 and reduce cholesterol build up and improve lysosomal function. However, LBPA is reported to be ineffective in reducing cholesterol build-up in NPC2 deficient cells.

Clone C64 is a ZooMAb^® mouse recombinant monoclonal antibody that detects lyso(bis)phosphatidic acid (LBPA).

Purified recombinant mouse monoclonal antibody IgG, lyophilized in PBS with 5% Trehalose, normal appearance a coarse or translucent resin. The PBS/trehalose components in the ZooMAb formulation can have the appearance of a semi-solid (bead like gel) after lyophilization. This is a normal phenomenon. Please follow the recommended reconstitution procedure in the data sheet to dissolve the semi-solid, bead-like, gel-appearing material. The resulting antibody solution is completely stable and functional as proven by full functional testing. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 μL.

Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 μL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.

Reconstitute lyophilized antibody pellet with 25μL of ultrapure water or Phosphate Buffered Saline (PBS). Please refer to our reconstitution protocol and the specific application guidance on the suggested starting dilutions and sample type.
