| 背景描述 | Galectin-13 (Gal-13) is a lectin family member and is one of the prototype galectins. It contains one carbohydrate recognition domain (CRD), responsible for β-galactoside binding, and is biologically active as homodimers. Galectin-13 is expressed in the placenta, contributing to T cell apoptosis, immune regulation, and immune tolerance, which is indispensable for fetal development. For example, galectin-13 organizes crystal-like aggregates in the decidua, consequently attracting and killing maternal immune cells. Furthermore, galectin-13 is essential for driving neutrophil polarization in the placental-growth-permissive phenotype. |

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. |
