General description
Poly(A) is used as a carrier for quantitative precipitation of DNA and RNA.
Application
Poly(A) has been used for droplet digital PCR (ddPCR) assay.
Polyadenylic acid (Poly(A)) to inhibit Exo1′s exonuclease activity. It has also been used as a carrier to resuspend lyophilized gBlocks.
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.
Quality
Typical analysis:
2.3μmol/mg Poly(A) (from absorbance) in relation to one mononucleotide unit. Chromatographically homogeneous.
Absorbance determination A250/A260, A280/A260, A290/A260

Precise genome-editing relies on the repair of sequence-specific nuclease-induced DNA nicking or double-strand breaks (DSBs) by homology-directed repair (HDR). However, nonhomologous end-joining (NHEJ), an error-prone repair, acts concurrently, reducing the rate of high-fidelity edits. The identification of genome-editing conditions that

Cells are under threat of osmotic perturbation; cell volume maintenance is critical in cerebral edema, inflammation and aging, in which prominent changes in intracellular or extracellular osmolality emerge. After osmotic stress-enforced cell swelling or shrinkage, the cells regulate intracellular osmolality

The mechanisms underlying ribonucleoprotein (RNP) granule assembly, including the basis for establishing and maintaining RNP granules with distinct composition, are unknown. One prominent type of RNP granule is the stress granule (SG), a dynamic and reversible cytoplasmic assembly formed in
