Protein sample prep strategies

This webinar will focus on different membrane protein solubilization strategies and what enrichment or purification is necessary depending upon the downstream mode of detection or analysis.

Featured protein purification & isolation categories

Resins for specific purification of proteins and other target molecules, kits for immunoprecipitation (IP), activated resins for covalent immobilization of ligands, and columns for packing affinity resins.

Invitrogen™ Dynabeads™ magnetic reagents for small-scale protein isolation and agarose-based beads for large-scale applications, including immunoprecipitation (IP) and co-immunoprecipitation (co-IP).

Specialized reagents designed for efficient organelle isolation, subcellular fractionation, and protein solubilization from a variety of cell and tissue types, protease inhibitors, phosphatase inhibitors, and detergents. 

Dialysis cassettes, desalting columns, concentrators, and other buffer-exchange devices for removing contaminants and concentrating samples to prepare them for long-term storage or to make them compatible with downstream applications.

Protease and phosphatase inhibitors, cocktails, and tablets—ideal for the protection of proteins during extraction or lysate preparation from primary cells, cultured mammalian cells, animal tissues, plant tissues, yeast, or bacterial cells.

Protein expression systems, including algae, bacterial, mammalian, insect, and yeast expression vector systems that are easy to use and deliver protein at high yield, and are suitable for nearly every downstream application.
