Amine Reactive Labeling. (May be suitable for use in other assays to be determined by the end user.)
Predicted isoelectric point: 6.7
 Ki-67蛋白(Ki67P)重组蛋白Predicted Molecular Mass: 18.3kDa
Accurate Molecular Mass: 15&26kDa as determined by SDS-PAGE reducing
conditions. Phenomenon explanation:
The possible reasons that the actual band size differs from the predicted are as
follows:
1. Splice variants: Alternative splicing may create different sized proteins from the same gene.
2. Relative charge: The composition of amino acids may affects the charge of the protein. 3. Post-translational modification: Phosphorylation, glycosylation, methylation etc. 4. Post-translation cleavage: Many proteins are synthesized as pro-proteins, and then cleaved to
give the active form. 5. Polymerization of the target protein: Dimerization, multimerization etc. [ USAGE ]
Reconstitute in PBS (pH7.4) to a concentration of 0.1-1.0 mg/mL. Do not vortex. [ STORAGE AND STABILITY ]
Storage: Avoid repeated freeze/thaw cycles. Store at 2-8
oC for one month. Aliquot and store at -80
oC for 12 months. Stability Test: The thermal stability is described by the loss rate. The loss rate
was determined by accelerated thermal degradation test, that is, incubate the
 Ki-67蛋白(Ki67P)重组蛋白protein at 37
oC for 48h, and no obvious degradation and precipitation were
observed.The loss rate is less than 5% within the expiration date under
appropriate storage condition. [ SEQUENCE ]
