Phosphatase and tensin homolog-long (PTEN-L) is a translational isoform of PTEN, which exists in both intracellular and extracellular locations. Previous studies demonstrated that PTEN-L could inhibit oncogenesis due to its lipid phosphatase activity. However, recent studies found that PTEN-L could promote the proliferation of some types of cancer cells. Moreover, as a protein phosphatase, PTEN-L can suppress mitophagy by counteracting PTEN-induced putative kinase protein 1 (PINK1)-Parkin-mediated ubiquitin phosphorylation, namely, PTEN-L is critical for exploring the mitophagy progression and the treatment of mitochondrial diseases. Accounting for the critical functions of PTEN-L, its antibody can be used for the treatment or prognosis of tumors and mitochondrial diseases. Currently, the com. antibody of PTEN-L is not available. In our study, the recombinant PTEN-L protein was expressed in Escherichia coli BL21 and used as an antigen to immunize Japan’s big-eared white rabbit for the preparation of polyclonal antibody. The PTEN-L protein can be captured by PTEN-L antibody specifically and effectively. Taken together, a PTEN_L antibody is a valuable tool for further exploring the function of PTEN-L in oncogenesis and mitochondrial diseases, and it would be a new choice for the prognosis or treatment of cancer and mitochondrial diseases. This study involved multiple reactions and reactants, such as (2R,3R,4S,5R,6S)-2-(Hydroxymethyl)-6-(isopropylthio)tetrahydro-2H-pyran-3,4,5-triol (cas: 367-93-1COA of Formula: C9H18O5S).
(2R,3R,4S,5R,6S)-2-(Hydroxymethyl)-6-(isopropylthio)tetrahydro-2H-pyran-3,4,5-triol (cas: 367-93-1) belongs to alcohols. Under appropriate conditions, inorganic acids also react with alcohols to form esters. To form these esters, a wide variety of specialized reagents and conditions can be used. Secondary alcohols are easily oxidized without breaking carbon-carbon bonds only as far as the ketone stage. No further oxidation is seen except under very stringent conditions.COA of Formula: C9H18O5S
