Anti-RRAS2 Antibody

This polyclonal antibody from Antibodies.com targets RRAS2, a Ras-related small GTPase involved in cell signaling, proliferation, and vesicle trafficking pathways. Raised in rabbit and supplied unconjugated, the reagent is validated for Western blot and immunohistochemistry workflows on tissue sections and cell lysates derived from human, mouse, and rat samples.

Each vial contains 100 µl of antibody at 1 mg/ml in PBS supplemented with 0.1% sodium azide and 50% glycerol as a cryoprotectant, supporting frozen storage with minimal loss of titer across multiple freeze-thaw cycles. The high glycerol content keeps the polyclonal pool liquid at working bench temperatures, reducing the need for repeated aliquoting during a typical experimental campaign.

RRAS2, also known as TC21, is a membrane-anchored GTPase sharing high homology with classical RAS family members, which makes this reagent useful for studies of receptor tyrosine kinase signaling, tumor cell migration, and downstream MAPK pathway activation. Researchers examining tissue-specific expression patterns in paraffin-embedded archival material can apply the antibody at optimized dilutions for chromogenic IHC detection, while whole-cell extract preparations are compatible with standard SDS-PAGE and Western blot protocols.
