| 背景描述 | PROS1, also known as protein S, is a vitamin K-dependent protein that plays a crucial role in the regulation of blood coagulation. It functions as a cofactor for protein C, another key player in the coagulation cascade. PROS1 acts as an anticoagulant by inhibiting the activity of certain clotting factors and promoting the breakdown of blood clots. It helps maintain the balance between clotting and anticoagulation, preventing the formation of excessive blood clots that can lead to thrombosis. |

1. Before opening, centrifuge at 3000 rpm for 5 mins.
2.Initial Reconstitution
· Reconstitute the Lyophilized Protein in sterile H₂O to a concentration of 100-200 μg/mL.
· Then, incubate it at room temperature for at least 20 mins to ensure sufficient dissolution.
Do Not Vortex! Vigorous shaking may impair the biological activity of the protein.
· Store at 2°C to 8°C for up to 1 week.
3.Extended Storage
· After the initial reconstitution, further dilute the reconstituted protein in a buffer containing a carrier protein or stabilizer (e.g., 0.1% BSA, 10% FBS, 5% HSA, or 5% trehalose solution). The final concentration is not less than 10 μg/ml.
· Prepare aliquots (≥20 μl).
· Store at -20°C or -80°C for 3 to 6 months.
Avoid repeated freeze-thaw cycles.
| 储存 | Lyophilized Protein: Store at -20°C for 1 year. Initial Reconstitution: Store at 2°C to 8°C for up to 1 week. Extended Storage: Store at -20°C or -80°C for 3 to 6 months with a carrier protein or stabilizer. |
