Poly(A)
Polyadenylic acid
General description
Poly(A)被用作DNA和RNA定量沉淀的载体。
Application
Polyadenylic acid (Poly(A)) to inhibit Exo1′s exonuclease activity. It has also been used as a carrier to resuspend lyophilized gBlocks.
Poly(A)已可用于微滴式数字PCR(ddPCR)分析。
Biochem/physiol Actions
Polyadenylic acid (Poly(A)) tails present at 3′ end are produced in the cell nucleus. It contains ~250 nucleotides in mammalian cells. Poly(A) regulates mRNA decay and the initiation of translation. Cytoplasmic poly(A) extension modulates translation.
