应用


  • Low molecular weight polystyrene standards for gel permeation chromatography: The characterization of branched ultrahigh molar mass polymers using asymmetrical flow field-flow fractionation and size exclusion chromatography highlighted the essential role of low molecular weight polystyrene standards in determining polymer distribution and characteristics, contributing significantly to advances in polymer science research (Otte et al., 2011).

组分

ReadyCal标准品是预先称重到自动进样瓶中的聚合物混合物,便于校准GPC/SEC/GFC系统。
该试剂盒包含10组3个颜色编码的小瓶,每个小瓶包含4个不同摩尔质量的聚苯乙烯。摩尔质量范围为~266至~66,000 Da,经过精心选择,以便痕量聚合物能被基线分离。
提供的材料足够至少10次校准。
适用于THF、甲苯、DMF、DMAc、氯仿、TCB、DCB和NMP的校准。

Lignin causes lignocellulosic biomass recalcitrance to enzymatic hydrolysis. Engineered low-lignin plants have reduced recalcitrance but often exhibit yield penalties, offsetting their gains in fermentable sugar yield. Here, CRISPR/Cas9-generated CCR2(-/*) line 12 poplars have one knockout CCR2 allele while the other
