Answer:Sulfoethyl groups provide strong cation-exchange functionality for binding positively charged proteins under suitable buffer conditions.
Answer:One prepacked HiTrap column with a 1 mL resin bed is supplied.
Answer:Yes. The 1 mL format supports comparison of loading, washing and salt-elution conditions on appropriately configured liquid chromatography equipment.
HiTrap Capto S is a prepacked strong cation-exchange chromatography column for the capture, intermediate purification and method development of proteins carrying a net positive charge under the selected buffer conditions. The 1 mL column contains Capto S resin with sulfoethyl functional groups on a robust agarose-based matrix. This compact format supports screening of binding pH, salt concentration and elution conditions before transferring an optimized process to larger columns. Clarify the sample, equilibrate the column in a suitable low-conductivity buffer and collect breakthrough and elution fractions for analysis. Protein selectivity depends on the relationship between working pH, sample ionic strength and the target protein’s charge properties.
