Ras-related protein Rab-27a (Rab27a) belongs to the small GTPase superfamily. The protein is membrane-bound and is involved in protein transport and small GTPase-mediated signal transduction. Rab27a plays a role in cytotoxic granule exocytosis in lymphocytes. Rab27a is widely expressed with considerable expression in pancreatic islets and pituitary tissue, and low expression in the brain. Defects in RAB27A are a cause of Griscelli syndrome type 2 (GS2), a rare autosomal recessive disorder.

Recommend starting dilution:
If reconstituted with deionized water in 100 μl: WB: 1:1000 (Recommended blocking solution: Donkey Serum 20%). IP: native conditions with 0.2% TritonX-100. Optimal dilution has to be determined by the user.
Lyophilized antibodies can be kept at 4ºC for up to 3 months and should be kept at -20ºC for long-term storage (2 years). To avoid freeze-thaw cycles, reconstituted antibodies should be aliquoted before freezing for long-term (1 year) storage (-80ºC) or kept at 4ºC for short-term usage (2 months). For maximum recovery of product, centrifuge the original vial prior to removing the cap. Further dilutions can be made with the assay buffer. After the maximum long-term storage period (2 years lyophilized or 1 year reconstituted) antibodies should be tested in your assay with a standard sample to verify if you have noticed any decrease in their efficacy.
