Small-scale Triton X-114 Extraction of Hydrophobic Proteins
Authors:  Yuzuru Taguchi and Hermann M. Schätzl, date: 06/05/2014, view: 7817, Q&A: 0
Here we introduce a protocol for Triton X-114 extraction which we used in our recently-published paper (Taguchi et al., 2013). It is a versatile method to concentrate or partially purify hydrophobic proteins. The presented protocol is based ...
Small-scale Subcellular Fractionation with Sucrose Step Gradient
Authors:  Yuzuru Taguchi and Hermann M. Schätzl, date: 06/05/2014, view: 6709, Q&A: 0
Here, we introduce the protocol for small-scale and simple subcellular fractionation used in our recent publication (Taguchi et al., 2013), which uses homogenization by passing through needles and sucrose step-gradient.
