This product is a trypsin analogue derived from microorganisms. It recognizes lysine or arginine residues and cleaves at the carboxyl‑terminal side of arginine or lysine residues. It contains no animal‑derived components and is free of animal‑sourced viral contaminants (e.g., swine influenza virus, porcine parvovirus, etc.). Naturally devoid of chymotrypsin‑like activity, it serves as an alternative to porcine or bovine trypsin. It digests cells gently, features stable properties and is easy to store.
Storage buffer: DPBS solution (containing 1.1 mM EDTA).
Product Application
Dissociation of adherent cells
Contents & Storage
| Component No. | Component Name | Appearance | 10mL | 100mL | 500mL | Storage |
| E1528001A | Recombinant trypsin‑analog digestion solution (10×, W/O Phenol Red) | Liquid | 10mL | 100mL | 500mL | 2-8℃. |
| E1528001B | 100×EDTA | Liquid | 2.5ml | 25ml | 125mL | 2-8℃. |
Procedure (For Reference Only)
1. Before use, dilute the 10× recombinant trypsin analogue digestion solution to working concentration using sterile DPBS (containing 1.1 mM EDTA). The recommended working concentration is 0.5×‑2×.
2. Pre‑warm the recombinant trypsin analogue working solution and complete medium at 37 ℃.
3. Discard culture supernatant. Wash cells with appropriate volume of DPBS and remove DPBS.
4. Add an appropriate volume of recombinant trypsin analogue working solution (0.5 mL per 10 cm²). Incubate at 37 ℃ until cells detach.
5. Add 5‑10 mL pre‑warmed complete medium, mix cells gently. Transfer cell suspension into a sterile 15 mL centrifuge tube and centrifuge at 100 g for 5‑10 min.
6. Discard supernatant and resuspend cells in adequate complete medium for further culture.
Notes
1. Recommendations for organoid dissociation: Allow 15 min digestion for cystic organoids; double the digestion time for solid organoids.
2. Store this product at 2‑8 ℃. If freezing is required under special circumstances, avoid repeated freeze‑thaw cycles.
3. Wear laboratory coat and disposable gloves during handling.
4. This product is not intended for direct clinical diagnosis or therapeutic use.
