Background: Calumenin is a secreted calcium-binding protein that belongs to the CREC family. Calumenin contains six EF-hand domains and is expressed at high levels in the heart; placenta and skeletal muscle. Human Calumenin is synthesized as a 315 amino acid precursor that contains a 19 amino acid signal sequence; and a 296 amino acid mature chain. Calumenin localizes to the endoplasmic reticulum (ER) and sarcoplasmic reticulum (SR) of mammalian tissues which plays a role in ER functions as protein folding and sorting. Calumenin is involved in the regulation of vitamin K-dependent carboxylation of multiple N-terminal glutamate residues. It seems to inhibit γ-carboxylase GGCX.
Sequence: Lys20-Phe315
Purity: > 95 % as determined by reducing SDS-PAGE.
Formulation: Lyophilized from a 0.2 μm filtered solution of 20mM PB; 150mM NaCl; pH7.4.
Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
Please refer to the specific buffer information in the printed manual.
Reconstitution: Please refer to the printed manual for detailed information.
Endotoxin: < 1.0 EU per μg of the protein as determined by the LAL method.
Calculated MW: 36.0 kDa
Observed MW: 54 kDa
Storage: Generally, lyophilized proteins are stable for up to 12 months when stored at -20 to -80℃. Reconstituted protein solution can be stored at 4-8℃ for 2-7 days. Aliquots of reconstituted samples are stable at < -20℃ for 3 months.
Shipping: This product is provided as lyophilized powder which is shipped with ice packs.
