observerd MW

Molecular Weight: Calculated MW: 23.9 kDa Observed MW (SDS-PAGE): 27 kDa Possible reasons why the actual band size differs from the predicted band size: 1. Splice variants. Alternative splicing may create different sized proteins from the same gene. 2. Relative charge. The composition of amino acids may affect the charge of the protein. 3. Post-translational modification. Phosphorylation, glycoslyation, methylation etc. may affect the band size. 4. Post-translational cleavage. Many proteins are synthesised as pro-proteins, and then cleaved to give the active form. 5. Polymerisation of the target protein. Dimerisation, multimerisation etc. will increase the band size observed. Concentration: Prior to lyophilization: 200 µg/ml Sequence Fragment: Gly25-Ser208 Tag: N-terminal His tag
