Lead (Pb)
Known as one of the oldest metals, native lead rarely occurs naturally. The most common lead-containing minerals are galena, anglesite, cerussite, and minim.
Lead is shiny, bluish-white, and very soft. It's highly malleable, ductile, and conducts electricity poorly. Natural lead is a mixture of four stable isotopes, all from the decay of naturally occurring radioactive elements.
The metal is used in solder, cable covering, plumbing, and ammunition, and as a radiation shield for X-ray equipment and nuclear reactors. Lead compounds are used in batteries, paints, crystal, and flint glass. It's also a cumulative poison and must be handled with care.

Cayman Chemical 2amIno5methyl4phenyl ThI 100mg
A potent inhibitor of PARP1 and PARP2 (IC50 5 and 1 nM respectively) but is less effective against the PARP tankyrase-1 (IC50 1 5 UM) can be used in cells and in animals alone or in combination therapy with alkylating agents to block BER and increase cancer cell death
