Storage & Solubility Information
| Description | KRAS Protein,Human, Recombinant (Q61H, His) is expressed in E. coli expression system with His tag. The predicted molecular weight is 22.5 kDa and the accession number is P01116-2. |
| Species | Human |
| Expression System | E. coli |
| Tag | N-His |
| Accession Number | P01116-2 |
| Construction | A DNA sequence encoding the human KRAS (P01116-2) (Thr2-Cys185, with natural variant Gln 61 His ) was expressed with a polyhistide tag at the N-terminus. Predicted N terminal: Met |
| Protein Purity | > 90 % as determined by SDS-PAGE https://cdn.targetmol.com/group3/M00/12/F1/CgoaEGZG0z6EVzHAAAAAAF7DzWE993.png |
| Endotoxin | Please contact us for more information. |
| Formulation | Lyophilized from a solution filtered through a 0.22 μm filter, containing 20 mM Tris, 0.5M NaCl, pH 7.5. Typically, a mixture containing 5% to 8% trehalose, mannitol, and 0.01% Tween 80 is incorporated as a protective agent before lyophilization. |
| Reconstitution | Reconstituted with sterile deionized water to 0.25 mg/mL. Reconstitution conditions may vary depending on the lot. |
| Stability & Storage | It is recommended to store recombinant proteins at -20°C to -80°C for future use. Lyophilized powders can be stably stored for over 12 months, while liquid products can be stored for 6-12 months at -80°C. For reconstituted protein solutions, the solution can be stored at -20°C to -80°C for at least 3 months. Please avoid multiple freeze-thaw cycles and store products in aliquots. |
| Shipping | In general, lyophilized powders are shipped with blue ice, while solutions are shipped with dry ice. |
| Synonyms | RASK2, RALD, NS3, NS, K-RAS4B, K-RAS4A, K-RAS2B, K-RAS2A, KRAS2, KRAS1, K-RAS, Kirsten rat sarcoma viral oncogene homolog, KI-RAS, C-K-RAS, CFC2 |
| Research Background |
| Molecular Weight | 22.5 kDa (predicted); 25 kDa (reducing conditions) |
| Storage | Lyophilized powder: -20~-80°C for 1 year | Solution: -80°C for 6 months |
