Recombinant Human Regenerating islet-derived protein 4/REG4 is produced by our mammalian expression system in human cells. The target protein is expressed with sequence (Asp23Pro158) of Human REG4 fused with a polyhistidine tag at the C-terminus.

Format
Lyophilized
Reconstitution
It is not recommended to reconstitute to a concentration less than 100 μg/mL. Dissolve the lyophilized protein in ddH2O. Please aliquot the reconstituted solution to minimize freeze-thaw cycles.
Buffer
Lyophilized from a 0.2 μm filtered solution of 20 mM PB,150 mM NaCl, pH 7.2.
Conseil sur la manipulation
Always centrifuge tubes before opening. Do not mix by vortex or pipetting.
Stock
4 °C/-20 °C/-80 °C
Stockage commentaire
Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks. Reconstituted protein solution can be stored at 4-7°C for 2-7 days. Aliquots of reconstituted samples are stable at < -20°C for 3 months.

Sujet
REG4 is a secreted contains one C-type lectin domain, high expressed in the gastrointestinal tract, including jejunum, ileum, appendix, pancreas and small intestine. REG4 can be up-regulated by mucosal injury from active Crohn’s disease or ulcerative colitis. In the acid environment, REG4 can maintain carbohydrate recognition activity. REG4 may be involved in inflammatory and metaplastic response of the gastrointestinal epithelium.
