TSP50 promotes the proliferation, migration and invasion of gastric cancer cells involving NF-kappaB dependent EMT activation. Targeting TSP50 may provide a novel therapeutic strategy for the management of gastric cancer PMID: 29361914
human epidermal growth factor receptor 2 (HER-2) levels, were correlated well with TSP50/p-Samd2/3 and TSP50/p27 expression status. Thus, our studies revealed a novel regulatory mechanism underlying TSP50-induced cell proliferation and provided a new favorable intervention target for the treatment of breast cancer PMID: 28650473

TSP50 plays a significant role in NSCLC cell proliferation and may act as a novel oncogene in the development and progression of NSCLC. PMID: 27109614
Results suggest that 7P3A, which consists of 70 % 25-methoxyl-dammarane-3beta, 12beta, 20-triol and 30 % artemisinin, exhibits anti-cancer effects, in part, through downregulation of testes-specific protease 50 (TSP50) expression. PMID: 27039397
Results show that TSP50 is up-regulated in laryngocarcinoma tumour tissues and its down-regulation inhibits cell proliferation, reduces cell migration and induces cell apoptosis of laryngocarcinoma in NF-KB mediated pathway. PMID: 25399078
we found that some breast cancer diagnosis-associated features such as tumor size, tumor grade, estrogen receptors (ER) and progesterone receptors (PR) levels, were correlated well with TSP50/p65 and TSP50/MMP9 expression status PMID: 25811800
TSP50's threonine protease activity is crucial for its effects on tumor formation. PMID: 25312478

TSP50 is a potential effective indicator of poor survival for colorectal carcinoma patients, especially for those with early-stage tumors. PMID: 21765952
Results strongly suggest that bFGF mediates TSP50 downregulation by ERK1/2 activation, leading to the phosphorylation of Sp1 in this process. PMID: 20506264
TSP50, a possible protease in human testes, is activated in breast cancer epithelial cells. PMID: 11782390
TSP50 was largely downregulated in all testicular germ cell tumors. It may function in mammalian spermatogenesis. Its linear catalytic structure is similar to many serine proteases, except for a Thr-for-Ser residual catalytic site substitution. PMID: 15491742
Overexpression of Sp1 and C/EBPbeta transcriptional factors upregulated the activities of the TSP50 promoter. PMID: 18462069
These findings suggested that DNA methylation might regulate the TSP50 and mTSP50 gene expressions in different types of tissues and spermatic cells. PMID: 18662669

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.
