Datasheet SDS
Recombinant CA125 is a recombinant Human protein produced in a Prokaryotic expression system (E. coli).

Target Carbohydrate Antigen 125 (CA125)
Origin Human
Expression Recombinant
Tested Applications WB, SDS-PAGE
Host E. coli
Conjugation Unconjugated
Form Lyophilized
Purity > 95%
Reconstitution To keep the original salt concentration, we recommend reconstituting to the original concentration prior to lyophilization (see Concentration) in ddH2O. If a lower concentration is required, dilute in 20 mM Tris, 150 mM NaCl, pH 8.0. If a higher concentration is required, the product can be reconstituted directly in 20 mM Tris, 150 mM NaCl, pH 8.0, though please note that this will change the overall salt concentration. The stock concentration should be between 0.1-1.0 mg/ml. Do not vortex.
Storage Store at 2-8 °C for up to one month. Store at -80 °C for up to one year. Avoid repeated freeze/thaw cycles.

UniProt Entry Name MUC16_HUMAN
KEGG hsa:94025
String 9606.ENSP00000381008
Molecular Weight Calculated MW: 22.2 kDa
Observed MW (SDS-PAGE): 26 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.
