应用
本分析标准用于以下方面：
- 通过不同流速、硅胶颗粒大小和柱孔大小评价粒径排除色谱（SEC）法分离完整蛋白的选择性和分离效率
- 通过粒径排除色谱-高效液相色谱-二极管阵列检测（SEC-HPLC-DAD）同时测定寡聚化和硝化蛋白
- 以牛血清白蛋白（BSA）作为模型蛋白，经 O3 和 NO2 诱导氧化、硝化和寡聚，通过尺寸排除层析法对蛋白质进行分子量分离
- 通过粒径排除色谱（SEC）法估算两种重组蛋白 TNF 荧光传感器（BTN-Kat）和荧光传感器抑制剂（ITN-Kat）的分子量，评估其在体外结合和中和肿瘤坏死因子（TNF）的能力，并进一步作为非侵入性分析的成像标记

In this work, we characterized 2 novel insecticidal proteins; Vip3Ab1 and Vip3Bc1. These proteins display unique insecticidal spectra and have differential rates of processing by lepidopteran digestive enzymes. Furthermore, we have found that both proteins exist as tetramers in their

Rhomboid-like proteins are intramembrane proteases with a variety of regulatory roles in cells. Though many rhomboid-like proteins are predicted in plants, their detailed molecular mechanisms or cellular functions are not yet known. Of the 13 predicted rhomboids in Arabidopsis thaliana

Single-chain variable fragments (scFvs), composed of variable domains of heavy and light chains of an antibody joined by a linker, share antigen binding capacity with their parental antibody. Due to intrinsically low solubility and stability, only two Escherichia coli-produced scFvs

Vip3A proteins are important for the control of spodopteran pests in crops, including Spodoptera frugiperda (fall armyworm). Native Vip3Ab1 controls S. frugiperda, but it is ineffective against S. eridania (southern armyworm), a major pest of soybean in South America. Recently
