Form	Liquid or Lyophilized powder
Buffer	Liquid form: default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. Lyophilized powder form: the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0.
Reconstitution	Briefly centrifuged the vial prior to opening to bring the contents to the bottom. Reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL. It is recommended to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. The default final concentration of glycerol is 50%.
Storage	1. Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. 2. Avoid repeated freeze-thaw cycles. 3. Store working aliquots at 4°C for up to one week. 4. In general, protein in liquid form is stable for up to 6 months at -20°C/-80°C. Protein in lyophilized powder form is stable for up to 12 months at -20°C/-80°C.
Notes	Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Gene Functions References

Thrombomodulin and RHBDL2 are upregulated in human HaCaT cells stimulated by scratch wounds; furthermore, increased solulbe thrombomodulin was found in culture medium. PMID: 21833011
RHBDL2 cleaves epidermal growth factor just outside its transmembrane domain, thereby facilitating its secretion and triggering activation of the epidermal growth factor receptor. PMID: 21494248
Substrate specificity of RHBDL2 intramembrane protease is governed by helix-breaking residues in the transmembrane domain. PMID: 12820957
Here, the authors show that RHBDL2 is produced as a proenzyme and that the processing of RHBDL2 is required for its cellular protease activity. PMID: 19850051
The encoded protein is thought to release soluble growth factors by proteolytic cleavage of certain membrane-bound substrates, including ephrin B2 and ephrin B3. PMID: 15047175

Proteins are sensitive to heat, and freeze-drying can preserve the activity of the majority of proteins. It improves protein stability, extends storage time, and reduces shipping costs. However, freeze-drying can also lead to the loss of the active portion of the protein and cause aggregation and denaturation issues. Nonetheless, these adverse effects can be minimized by incorporating protective agents such as stabilizers, additives, and excipients, and by carefully controlling various lyophilization conditions.

Commonly used protectant include saccharides, polyols, polymers, surfactants, some proteins and amino acids etc. We usually add 8% (mass ratio by volume) of trehalose and mannitol as lyoprotectant. Trehalose can significantly prevent the alter of the protein secondary structure, the extension and aggregation of proteins during freeze-drying process; mannitol is also a universal applied protectant and fillers, which can reduce the aggregation of certain proteins after lyophilization.

Our protein products do not contain carrier protein or other additives (such as bovine serum albumin (BSA), human serum albumin (HSA) and sucrose, etc., and when lyophilized with the solution with the lowest salt content, they often cannot form A white grid structure, but a small amount of protein is deposited in the tube during the freeze-drying process, forming a thin or invisible transparent protein layer.

Reminder: Before opening the tube cap, we recommend that you quickly centrifuge for 20-30 seconds in a small centrifuge, so that the protein attached to the tube cap or the tube wall can be aggregated at the bottom of the tube. Our quality control procedures ensure that each tube contains the correct amount of protein, and although sometimes you can't see the protein powder, the amount of protein in the tube is still very precise.
