| Description | S3 Fragment is a biological active peptide. (This peptide contains the unique amino-terminal phosphorylation site of Xenopus ADF/cofilin, the LIM kinase (LIMK) phosphorylation site. LIMK1 is a key regulator of the actin cytoskeleton through its phosphorylation of ADF/cofilin at serine-3 for S3 Fragment is a biological active peptide. (This peptide contains the unique amino-terminal phosphorylation site of Xenopus ADF/cofilin, the LIM kinase (LIMK) phosphorylation site. LIMK1 is a key regulator of the actin cytoskeleton through its phosphorylation of ADF/cofilin at serine-3 for inactivation. This peptide is a fragment of the S3 peptide containing the serine-3 sequence of ADF/cofilin that has been widely used as an effective competitive inhibitor of LIMK1.)...

Anthopleurin-A TFA can be isolated from the sea anemone[1][2] | Lambda DNA (λ DNA) is the DNA in λ phages and is used as a substrate for restriction endonucleases. This product is methylated Lambda DNA | Mastoparan X is a GTP-binding regulatory protein (G protein)-activating peptide, and a tetradecapeptide from wasp venom. Mastoparan X acts function by the direct activation of G protein that couple to phospholipase C to cause secretion from various kinds of cells[1] |
