DescriptionRecombinant human PAG / Cbp is expressed in E. coli.DNA sequence encoding intracellular domain of human Cbp/PAG (amino acids 41- 432) was fused with a His tag at the N-terminus.A calculated molecular mass of fussion protein is 45.3 kDa. As a result of highly acidic character of Cbp/PAG (predicted isoelectric point pI 4.4) and further modification by phosphorylation, the recombinant protein migrates as a 70 - 85 kDa protein in SDS-PAGE under reducing conditions.
ContentsRecombinant human PAG / Cbp - 1 vial (0.1 mg).Reconstitute vial content with 100 μl sterile deionized water. For long term storage or for preparation of more diluted working stock solution, a carrier protein (e.g. 1% serum albumin) should be added to the vial.
PreparationThe protein was purified by immobilized metal affinity chromatography used for purification of polyhistidine-tagged recombinant proteins, and lyophilized.
FormulationLyophilized from a 0.22 μm filtered solution in phosphate buffered saline (PBS).
Storage and handlingStore lyophilized product in freezer (-20 °C to -80 °C). The expiration date of unopened product vial is indicated on the vial label. After reconstitution prepare suitable aliquots. Reconstituted product is stable for at least 6 months when stored in freezer (-20 °C to -80 °C). Avoid freeze/thaw cycles.
