This chapter describes the principles and practices of centrifugation techniques. There are three main types of centrifugal fractionation, namely, (1) differential pelleting (differential centrifugation); (2) rate-zonal density-gradient sedimentation; and (3) isopycnic density-gradient sedimentation. Of ...

Our proprietary preparation obtained by extraction of Chlorella pyrenoidosa cells, ONC-107 (Respondin), was recently found to selectively boost antibody response to the influenza vaccine in a human clinical trial. Respondin is a potent stimulator of mouse B cell proliferation and an activator of mac...
Use of other fraction sizes (eg, 1.8 Gy, conventional), radiotherapy and chemotherapy for high-risk squamous-cell carcinoma of multiagent chemotherapy, or altered fractionation with chemotherapy has been evaluated the head and neck. with no consensus on the optimal approach. In general, the use ...
To interrogate the effects of cis-regulatory elements of RNA editing, we applied the CRISPR/Cas9 technology (Fig. 1a) to introduce mutations at the endogenous loci of three natural ADAR1 substrates (NEIL1, TTYH2, and AJUBA; Fig. 1b, see “Methods”). The mutations were introduced both in...

Figure 1. Workflow of the LiP-SMap Approach (A) Whole-cell lysates extracted under native lysis conditions are treated or not with a metabolite. Metabolite binding to a protein alters local proteolytic susceptibility. A limited proteolysis step is performed with proteinase K (PK) under native cond...

The strain necessary to rupture a cell is a function of time of the applied strain (Hategan etal., 2003, Li etal., 2013). Large cellular deformations (more than 150% stretching) are generated in the presence of histotripsy bubbles (Vlaisavljevich etal. 2016d). Although cells in the ...
