The GAS7 Isoform b is produced in Escherichia coli (E. coli) as a single, non-glycosylated polypeptide chain containing 436 amino acids. It has a molecular mass of approximately 49.8 kDa. The recombinant protein is fused to a 20 amino acid His Tag at the N-terminus, which facilitates its purification through chromatographic techniques .
GAS7 is primarily expressed in the brain and is believed to play a crucial role in the development and maintenance of the nervous system. It is involved in the regulation of neuronal differentiation and neurite outgrowth. The protein has been implicated in various cellular processes, including:
The recombinant form of GAS7 Isoform b is used in various research applications, including:
The recombinant GAS7 Isoform b protein is typically stored at 4°C if it is to be used within 2-4 weeks. For longer-term storage, it is recommended to store the protein at -20°C with the addition of a carrier protein such as 0.1% Human Serum Albumin (HSA) or Bovine Serum Albumin (BSA) to prevent degradation. It is important to avoid multiple freeze-thaw cycles to maintain the protein’s stability and activity .
