Introduction
Hematological and neurological expressed 1 protein (HN1) is a highly conserved protein found across various species. It plays a role in neural tissue regeneration, as evidenced by its increased expression in damaged nerve cells. HN1 is also present during embryonic development and in areas of the adult brain associated with adaptability.
Description
This recombinant HN1 protein is produced in E. coli and consists of a single chain of 174 amino acids (specifically, amino acids 1 to 154 of the human HN1 sequence), resulting in a molecular weight of 18.1kDa. For purification and detection purposes, a 20 amino acid His-tag is attached to the protein's N-terminus. The protein is purified using specialized chromatographic methods.
Physical Appearance
Clear and sterile solution.
Formulation
The HN1 protein is provided at a concentration of 0.5mg/ml in a solution containing 20mM Tris-HCl buffer (pH 8.0), 0.1M NaCl, and 10% glycerol.
Stability
For short-term storage (up to 4 weeks), keep the protein at 4°C. For longer periods, freeze the protein at -20°C. Adding a carrier protein like HSA or BSA (0.1%) is recommended for long-term storage. Avoid repeated freezing and thawing.
Purity
The purity of this protein is greater than 90% as determined by SDS-PAGE analysis.
Synonyms
ARM2, HN1A, Hematological and neurological expressed 1 protein, Androgen-regulated protein 2, HN1.
