Description
AccuBand™ 100 bp+3K DNA Ladder II is composed of 14 individual DNA fragments, presenting 3k, 2k, 1.5k, 1.2k, 1k, 900, 800, 700 600, 500, 400, 300, 200 and 100 bp sharp bands respectively. This product contains 2 enhanced bands (1k and 500 bp) for easy band identification. AccuBand™ 100 bp+3K DNA Ladder II is ready-to-use, containing loading buffer with dual color tracking dyes (orange G and Xylene cyanol FF). AccuBand™ 100 bp+3K DNA Ladder II provides a sufficient amount of DNA for clear observation of all DNA bands ranging from 100 bp to 3 kb, either in agarose gel or in polyacrylamide gel electrophoresis.

PEG13-bis(Amino-Tri-(Propargyl-PEG2-ethoxymethyl)-methane) is large molecule with two sets of three terminal alkynes joined together by a large PEG linker. The alkynes are most frequently used in copper click chemistry with azides. The PEG linkers as well as numerous amide bonds provide high aqueous solubility to this compound, which may alter ADME of this compound.
