Recombinant Human Cornulin (N-6His)

Cat.No.: C117

Recombinant Human Cornulin (N-6His)
Description
Recombinant Human Cornulin is produced by our E.coli expression system and the target gene encoding Met1-Ser140 is expressed with a 6His tag at the N-terminus.
Accession #:Q9UBG3
Known as:Cornulin; 53 kDa Putative Calcium-Binding Protein; 53 kDa Squamous Epithelial-Induced Stress Protein; 58 kDa Heat Shock Protein; Squamous Epithelial Heat Shock Protein 53; Tumor-Related Protein; CRNN; C1orf10; DRC1; PDRC1; SEP53
Formulation
Lyophilized from a 0.2 μm filtered solution of PBS, pH7.4.
Quality Control
Purity:Greater than 95% as determined by reducing SDS-PAGE.
Endotoxin:Less than 0.1 ng/µg (1 EU/µg) as determined by LAL test.
Reconstitution
Always centrifuge tubes before opening. Do not mix by vortex or pipetting.
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.
Storage
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.
Background
Cornulin is a member of the fused gene family of molecular chaperones. Human Cornulin contains N-terminus EF-hand domains and Ca2+ binding domains, and two glutamine- and threonine-rich 60 amino acid repeats in its C-terminus. Cornulin involves in the mucosal/epithelial immune response and epidermal differentiation. Cornulin is a survival factor that participates in the clonogenicity of squamous esophageal epithelium cell lines, attenuates deoxycholic acid (DCA)-induced apoptotic cell death and release of calcium. When Cornulin is overexpressed in oral squamous carcinoma cell lines, it regulates negatively cell proliferation by the induction of G1 arrest.
