| 背景描述 | Granulocyte Colony-Stimulating Factor (G-CSF) is a 18.67 kDa protein containing 207 amino acid which secreted by monocytes, macrophages, fibroblasts, and endothelial cells, regulates cell growth, maturation, and development of myeloid cells. G-CSF is a member of the CSF family of glycoproteins, and makes the bone marrow produce more white blood cells so it can reduce the risk of infection after some types of cancer treatment. G-CSF is also an established useful clinical agent for increasing neutrophilic granulocytes levels. Mouse G-CSF shares 73% sequence homology with human G-CSF. |

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. |
