Protein Purification
Protein Purification Services
Rx Biosciences provides expert protein purification services using bacterial, yeast, insect, and mammalian expression systems. From gene design and codon optimization to synthesis, cloning, and expression, we offer complete solutions. Our purification techniques include gravity flow columns, low-pressure systems, and FPLC using Cytiva GE AKTA. Purity is verified by SDS-PAGE and size-exclusion chromatography (SEC) profiling.
