Butyl Seplife 4FF Hydrophobic Interaction Medium,>26 mg HSA/mL (CAT#: STEM-BC-3136-ZJF)

This butyl hydrophobic interaction medium is designed for purification of hepatitis B vaccine products. It uses a four-percent agarose matrix functionalized with butyl groups. Hydrophobic interactions enable selective binding of target biomolecules under elevated salt conditions. Lowering the salt concentration releases bound components according to hydrophobic strength. The spherical particles support consistent column packing and reproducible operation. Protein adsorption above 26 mg HSA/mL provides useful preparative capacity. The medium operates at 150-250 cm/h under the stated pressure condition. Broad pH and chemical stability support repeated cleaning and regeneration. It can tolerate steam treatment under the specified saline conditions.
