ZooMAb^® antibodies represent an entirely new generation of recombinant monoclonal antibodies. Each ZooMAb^® antibody is manufactured using our proprietary recombinant expression system, purified to homogeneity, and precisely dispensed to produce robust and highly reproducible lot-to-lot consistency. Only top-performing clones are released for use by researchers. Each antibody is validated for high specificity and affinity across multiple applications, including its most commonly used application. ZooMAb^® antibodies are reliably available and ready to ship when you need them.

Target description

Lysosome-associated membrane glycoprotein 2 (UniProt: P13473; also known as LAMP-2, Lysosome-associated membrane protein 2, CD107 antigen-like family member B, LGP-96, CD107b) is encoded by the LAMP2 gene (Gene ID: 3920) in human. LAMP-2 is a single-pass type I, heavily glycosylated, membrane protein found in plasma membrane, endosomes, and lysosomes. It is synthesized with a signal peptide (aa 1-28), which is subsequently cleaved off to generate the mature form that contains a lumenal domain (aa 29-375), a transmembrane domain (aa 376-399), and a short cytoplasmic tail (aa 400-410). It is an important component of lysosomal membranes and is involved in both autophagy and lysosomal membrane permeabilization. LAMP-2 plays an important role in chaperone-mediated autophagy. It is required for the fusion of autophagosomes with lysosomes during autophagy. It also plays a role in lysosomal protein degradation in response to starvation. It functions by binding target proteins, such as GAPDH and MLLT11, and targets them for lysosomal degradation. In cancer cells, chronic acidosis-induced upregulation of LAMP-2 has been reported that protects these cells from acid-induced hydrolysis and promotes their survival via chaperone-mediated autophagy. Loss of LAMP-2 is reported to aggravate oxidative stress through the obstruction of reactive oxygen species clearance. Three different isoforms of LAMP-2 have been described that are produced by alternative splicing. Mutations in LAMP2 gene have been linked to Danon disease that is characterized by cardiomyopathy, vascular myopathy, and mental retardation. It is often associated with accumulation of glycogen in muscle and lysosomes. This ZooMAb^® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Physical form

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.

Reconstitution

300 µg/mL after reconstitution at 25 µL per vial. Please refer to guidance on suggested starting dilutions and/or titers per application and sample type.

Storage and Stability

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.
