Revvity AlphaLISA SureFire Ultra Human and Mouse Total HRAS Detection Kit, 100 Assay Points

Harvey Rat Sarcoma Viral Oncogene Homolog (HRAS) is a small GTPase that functions as a molecular switch in signal transduction pathways controlling cell proliferation, differentiation, and survival. HRAS cycles between inactive GDP-bound and active GTP-bound states, with activation triggered by receptor tyrosine kinases through guanine nucleotide exchange factors (GEFs). Activated HRAS engages multiple effector pathways including RAF/MEK/ERK, PI3K/AKT, and RAL-GDS cascades. Activating mutations in HRAS, particularly at codons 12, 13, and 61, impair GTPase activity resulting in constitutive signaling and oncogenic transformation. HRAS mutations are found in bladder cancer, head and neck squamous cell carcinoma, and Costello syndrome, a developmental disorder with increased cancer risk. Targeting mutant RAS proteins has been challenging, but recent development of KRAS G12C inhibitors has renewed interest in drugging the RAS family.

The AlphaLISA SureFire Ultra Human and Mouse Total HRAS Detection Kit is a sandwich immunoassay for the quantitative detection of total HRAS in cellular lysates, using Alpha Technology.
