Database References	HGNC: 21043 OMIM: 600977 KEGG: hsa:83394 STRING: 9606.ENSP00000262483 UniGene: PMID: 26756176 CCL18 enhances hepatocellular carcinoma (HCC) cell migration, invasion, and epithelial-mesenchymal transition (EMT) through the expression of PITPNM3 and the activation of the NF-kappaB signaling pathway. PMID: 26449829 Data indicate that PYK2 N-terminal domain interacting receptor 1 (Nir1) could induce epithelial-mesenchymal transition by stabilising Snail via the PI3K/Akt/GSK3beta/Snail signalling pathway through binding to CCL18. PMID: 24001613 Our observations of the PITPNM3 p.Q626H mutation carriers confirm that CORD5 is a disease not to mix with other retinal degenerations mapped to 17p13. PMID: 22405330 CCL18 derived from Tumor-associated macrophages (TAMs) lays a critical role in promoting breast cancer metastasis via its receptor, PITPNM3. PMID: 21481794 Thus, mutations in PITPNM3 do not appear to be a major cause of cone or cone-rod dystrophy. PMID: 20590364 Our finding on the first mutation in the human homologue of Drosophila rdgB indicates novel pathways and a potential important role of the PITPNM3 in mammalian phototransduction.

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.
