Human FAM49B ELISA Kit (HUFI04337)

FAM49B, also known as CYRI-B, is a cytoplasmic regulator of the small GTPase Rac1 and plays a key role in actin cytoskeleton remodeling, cell migration, and immune cell signaling. Researchers use this Assay Genie ELISA to quantify FAM49B levels in human blood-derived samples, supporting studies in oncology, immunology, and cell biology where altered Rac1 pathway activity has been linked to tumor invasion, T-cell activation defects, and inflammatory responses.

The kit is supplied as a complete reagent set in a microplate format with pre-coated wells, lyophilized standards, detection antibody, and assay buffers sufficient for the full plate run. Reconstituted standards and unused strips should be stored at -20 °C to preserve activity, while the sealed kit is shipped refrigerated and remains stable through the printed shelf life when handled according to the protocol. Each batch is validated against recombinant human FAM49B to ensure consistent standard curve performance across runs.
