EndoTrap red 10 (10 ml settled resin) Endotoxin Removal Resin. EndoTrap removes endotoxins (lipopolysaccharides/LPS) from aqueous solutions of a wide range of samples such as proteins, antibodies, vaccines, nucleic acids, buffers and cell extracts with excellent sample recovery rate. EndoTrap has been used in more than 200 publications. Endotoxin removal with EndoTrap red works effectively in the pH range of 6-9 and NaCl concentrations in the range of 50-250 mM. Buffers such as HEPES, PBS, TRIS, MOPS, MES, PIPES and also Citrate, Acetate, Glycine and Carbonate buffers are recommended. EndoTrap red can be used with chelators of divalent cations (like EDTA). Phosphate buffers with NaCl concentrations below 100 mM are recommended for EndoTrap red. FEATURES: LPS binding capacity: 2X10^6 EU/ml resin. Reusable up to 3 times. pH sample range: 6-9. Especially developed for Calcium chelators and low salt conditions. EndoTrap red is manufactured by LIONEX GmbH in Germany.
