背景描述 | Human CD27L is also named for CD70 which is one member of TNF family. Human CD27L is expressed on T and B lymphocytes and mature DCs. It binds the CD27, which is on the antigen-presenting cells. Human CD27L is a 23 kDa cytokine with 154 amino acid residues which is a transmembrane glycoprotein. Human CD27L plays an important role in the regulation of T cell proliferation which is also a good target of cancer immunotherapy. |

产品应用 | Cell Culture |
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. |
