Latest Questions
What is the final delivery form?
You can choose liquid form or lyophilized powder, Protein lyophilization incurs an additional fee. Lyophilized powder is reconstituted with deionized sterile water; fully dissolve it. The specific concentration depends on your experimental requirements.
Why is there a discrepancy between the actual and theoretical molecular weights?
1.Post-translational modifications such as phosphorylation and glycosylation can increase molecular weight.
2.Post-translational cleavage by the protein itself can decrease molecular weight.
3.Some proteins have several splice variants, each with a different molecular weight; these should be distinguished.
4.Related to the amino acid composition (charged vs. non-charged).
5.Formation of multimers can increase molecular weight.
