This product is a trypsin analog derived from microorganisms. It recognizes lysine or arginine residues and cleaves at the carboxyl terminal of lysine and arginine residues. It contains no animal-derived components and is free of animal-origin viral contaminants (e.g., swine influenza virus, porcine parvovirus). Naturally devoid of chymotrypsin activity, it serves as an alternative to porcine or bovine trypsin. This reagent enables gentle cell dissociation and features stable properties for convenient storage.
Storage buffer: DPBS containing 1.1 mM EDTA.
Product Applications
Dissociation of adherent cells
Protocol (For Reference Only)
Pre-warm Recombinant Trypsin LS and complete medium to 37 ℃ prior to use.
1. Discard culture supernatant, rinse cells with an appropriate volume of DPBS, then remove the DPBS.
2. Add an adequate amount of Recombinant Trypsin LS (0.5 mL per 10 cm²), incubate at 37 ℃ until cells detach.
3. Add 5–10 mL pre-warmed complete medium and gently resuspend cells. Transfer the cell suspension into a sterile 15 mL centrifuge tube, and centrifuge at 100 g for 5–10 minutes.
4. Remove the supernatant and resuspend the cell pellet with fresh complete medium for subsequent culture.
Precautions
1. Guidelines for organoid dissociation: incubate cystic organoids for 15 minutes; double the incubation time for solid organoids.
2. Store the product at 2–8 ℃. If cryopreservation is necessary under special circumstances, avoid repeated freeze-thaw cycles.
3. Wear a lab coat and disposable gloves during operation.
4. This product is not intended for direct clinical diagnosis or therapeutic use.
