| 背景描述 | Galectin-3 (Gal-3) is one of the lectin family members, which is the only chimera‑type galectin, containing one carbohydrate recognition domain (CRD) connected to a long, flexible N‑terminal domain. The C‑terminal CRD is responsible for β-galactoside binding, and the N‑terminal domain is essential for its multimerization, and interaction with other intracellular proteins. Galectin-3 is predominantly presented in the cytoplasm and expressed on the cell surface, and then often secreted into biological fluids, such as serum and urine. Numerous studies have indicated that galectin-3 plays a crucial role in cell proliferation, apoptosis, gene expression, immune surveillance, inflammation, fibrosis, and host defense. |

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. |
