HY-164421

PhpC	G-quadruplex DNA/RNA Synthesis	Cancer
PhpC is a G-quadruplex (G4)-DNA/RNA disruptor. PhpC disrupts DNA and RNA G4 structures and promotes G4 helicase activity. PhpC effectively enhancing the activity of Taq polymerase. PhpC modulates G-quadruplexs (G4s) both in vitro and in cells .

TMPyP tetrachloride	DNA Alkylator/Crosslinker Photosensitizer	Infection Cancer
TMPyP tetrachloride is a DNA-binding agent, singlet oxygen Sensitizer and photobleaching agent. TMPyP tetrachloride binds to DNA via intercalation or external groove complexation; irradiation induces its photoinduced release from DNA. TMPyP tetrachloride sensitizes the generation of singlet molecular oxygen upon irradiation, and prolonged irradiation leads to photobleaching. TMPyP tetrachloride initially localizes preferentially in neuronal nuclei and cytoplasm, and irradiation triggers its subcellular relocalization. TMPyP tetrachloride binds to K ⁺-free single-molecule G4-DNA nanowires via intercalation, and binds to K ⁺-type variants via non-intercalation. TMPyP tetrachloride can be used in studies related to cancer, HIV infection and bacterial infection .

Western blot analysis of extracts from THP-1(lane 2(20μg), Jurkat (lane 3(20μg) and NIH3T3(lane 4(20μg) using FOXO1A (HY-P80132) Rabbit mAb. Proteins were transferred to a PVDF membrane and blocked with 5% non-fat milk in TBST for 2 hour at room temperature. The primary antibody (1/1000) and Loading control antibody (Beta Actin, HY-P80438, 1/10000) was used in 5% non-fat milk in TBST at 4°C overnight. Goat Anti-Mouse/Rabbit IgG-HRP Secondary Antibody (1/10000) was used for 1 hour at room temperature.
