La-related protein 1 (UniProt: Q6PKG0; also known as La ribonucleoprotein domain family member 1) is encoded by the LARP1 (also known as KIAA0731, LARP) gene (Gene ID: 23367) in human. La-related protein 1 (LARP1) is a cytoplasmic RNA-binding protein that promotes translation of specific classes of mRNAs downstream of the mTORC1 complex. It contains 1 HTH La-type RNA-binding domain (aa 397-487) and it associates with the mRNA 5′cap in an mTOR-dependent manner. It associates with mRNAs containing a 5′ terminal oligopyrimidine (5′TOP) motif, which is present in mRNAs encoding for ribosomal proteins and several components of the translation machinery. It is also shown to associate with actively translating ribosomes via interaction with polyadenylate-binding protein 1 (PABPC1/PABP) and stimulate translation of mRNAs containing a 5′TOP, thereby regulating cell growth and proliferation. LARP1 undergoes phosphorylation on multiple serine and threonine residues in response to active mTORC1. These phosphorylations are important for interaction with RPTOR and the mTORC1 complex. Phosphorylation also promotes dissociation from the 5′UTR of mRNA molecules with a 5′TOP motif. LARP1 levels are up-regulated in a number of hepatocellular carcinoma cell lines and liver cancer lesions, as well as in patients with hepatocellular carcinoma with a lower survival rate. Two isoforms of LARP1 have been described that are produced by alternative splicing. This ZooMAb^® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS, 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.

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.

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.
