Target description

GTPase HRas (UniProt: P01112; also known as EC:3.6.5.2, H-Ras-1, Ha-Ras, Transforming protein p21, c-H-ras, p21ras) is encoded by the HRAS (also known as HRAS1) gene (Gene ID: 3265) in human. The RAS oncogene family consists of three members, HRAS, KRAS, and NRAS that encode membrane-associated proteins involved in mediation of signals arising from cell-membrane receptor tyrosine kinases and G-protein-coupled receptors along the MAPK, PI3K/AKT and other signaling pathways. Ras proteins bind GDP/GTP and possess intrinsic GTPase activity. H-Ras is widely expressed small G-protein that is synthesized with a propeptide (aa 187-189), which is subsequently cleaved off to produce the mature form that alternates between an inactive form bound to GDP and an active form bound to GTP. It is activated by a guanine nucleotide-exchange factor (GEF) and is inactivated by a GTPase-activating protein (GAP). The active GTP-bound form is localized most strongly to membranes than the inactive GDP-bound form. Acetylation at lysine 104 is reported to prevent interaction with GEFs. H-Ras is known to undergo palmitoylation at cysteines 181 and 184, directly upstream of the CAAX motif, as the final step of its activation prior to membrane localization. H-Ras contains a highly conserved G domain (aa 1-165) and a hypervariable region (aa 166-185). The G domain contains the vital switch I and II domains within its effector lobe (aa 1-86), an area that is conserved across all Ras isoforms. This region is responsible for allowing Ras to interact with effector protein pathways, primarily Raf-MEK-ERK and PI3K/AKT, to mediate cell growth, survival, and proliferation. This domain also the most common sites (G12, G13, and Q61) of Ras oncogenic mutations. The three RAS genes account for the most frequently mutated oncogene family in human cancers. This ZooMAbZooMAb® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Physical form

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.

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.
