    We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.

    8. Results show that TM4SF1 expression is elevated in colorectal cancer (CRC), and associated with tumor stage and lymph node metastasis. Also, miR-9 directly targeted its binding site in the TM4SF1 3'-UTR, which has a critical role in regulating CRC cell migration. and invasion. Furthermore, miR-9 regulated cell motility via suppressing PMID: 26983891
    9. The findings suggest that TM4SF1 is a surface membrane antigen that is highly expressed in pancreatic cancer cells and increases the chemoresistance to gemcitabine. TM4SF1 may be a promising target to overcome the chemoresistance of pancreatic cancer. PMID: 26709920
    10. TM4SF1 overexpression significantly contributed MDA-MB-231 cell migration but decreased apoptotic cells PMID: 26464650
    11. Study shows that TM4SF1 expression is associated with better prognosis in pancreatic cancer. Its loss contributes to the invasion and migration of pancreatic cancer cells. PMID: 26035794

    16. High TM4SF1 expression is associated with pancreatic cancer. PMID: 24285464
    17. TM4SF1, like genuine tetraspanins, serves as a molecular organizer that interacts with membrane and cytoskeleton-associated proteins and uniquely initiates the formation of nanopodia and facilitates cell polarization and migration. PMID: 21626280
    18. We provide evidence that ARHGDIA, COBLL1, and TM4SF1 are negative regulators of apoptosis in cultured tumor cells. PMID: 21569526
