产品属性:
Silwet L-77 is a chemical mixture of polyalkyleneoxide modified heptamethyltrisiloxane (84%) and allyloxypolyethyleneglycol methyl ether (16%). It is an essential infiltration media ingredient for all Agrobacterium-based transformations of Arabidopsis and other plants. 10 mL and 35 mL are sufficient quantity to prepare 33 L and 115 L of vacuum infiltration medium when used at the recommended rate of 0.03%, v/v, respectively.
