Protein Name & Synonyms:
Calcitonin gene-related peptide 1, Alpha-type CGRP, Calcitonin gene-related peptide I, CGRP-I, Calcitonin-Related Polypeptide Alpha, CALC1, Calcitonin 1, Calcitonin, Calcitonin/Calcitonin-Related Polypeptide, Alpha, Katacalcin, CGRP1, CGRP, KC, CT
Human Embryonic Kidney 293 Cells
N-terminal 6x histidine tag and C-terminal mouse IgG Fc tag
His-tag affinity purification by immobilized metal ion affinity chromatography (IMAC)
Purity determined by:
SDS-PAGE under reducing conditions and visualized by Coomassie blue staining
Molecular Weight (kDa):
Recombinant human calcitonin (CT) has a calculated molecular mass of 30 kDa (including a C-terminal mouse IgG Fc tag, 27 kDa). Due to the abundant glycosylation, it migrates as approximately 35-45 kDa protein bands in SDS-PAGE under DTT, beta-mercaptoethanol reducing conditions.
Lyophilized from a 0.2 um filtered solution in PBS
Determined by BCA protein assay kit (Thermo Scientific)
Briefly spin the vial and bring the contents to the bottom prior to opening. It is recommended to reconstitute at 0.5 - 1.0 mg/mL with sterile deionized water or 1x PBS.
Upon arrival, the protein may be stored for 2 weeks at 4 °C. For long term storage, it is recommended to store at -20 °C or -80 °C in appropriate aliquots. Avoid repeated freeze-thaw cycles.
