A new low-potential iron-containing electron-transfer protein has been isolated from cell free extracts of rumen bacteria. This protein, like some bacterial ferredoxins, can 1) transfer electrons from illuminated spinach chloroplasts to NADP; 2) catalyze ferredoxin dependent reductive carboxylation ...
The Hib bacteria are a single serotype (b) with several licensed Hib conjugate vaccines (HibCV)196 with different carrier proteins (TT, diphtheria toxoid, CRM197, and an outer membrane protein complex from N. meningitidis) of different sizes, distinct polysaccharide chain lengths and distinct conju...
Protocol for purification of inclusion bodies & protein refolding at Profacgen Step 1. Preparation of inclusion bodies: a. Harvest bacteria after induction. b. Lyse bacteria by sonication in the buffer containing Tri-HCl, NaCl, EDTA, NaN3, Triton-X100, PMSF and DTT. 50 ml aliquot usually wor...
Adsorption to the cell surface is the first step in the phage life cycle. Prevention of adsorption through modification of surface receptors serving as phage entry points is the first line of defence for bacteria, and it is a prevalent target for phage resistance mechanisms11. Bacteria thwart pha...
However, many membrane proteins do not form a functional complex in a heterologous system, and few methods exist to purify sufficient protein from a native source for use in biochemical, biophysical and structural studies. Here, we provide a detailed protocol for the isolation of membrane protein ...
Proteins can come from many sources, including the following: native sources such as mammalian cell cultures, tissues or bodily fluids; overexpression in a model system such as bacteria, yeast, insect or mammalian cells...

Therefore, after a comprehensive analysis of the MAGs of the gut microbiota in giant pandas, we next investigated the gene expression profiles of the active bacteria in the giant pandas by meta-transcriptomic sequencing of 14 fecal samples from captive giant pandas. Of note, these 14 samples ...
Second, there is no need to separate free RNAs on urea–PAGE, which is a necessary step to separate linker−linker ligation from previous CLIP protocol. Third, the usage of high concentration of RNA linkers can be avoided, which alleviates the aforementioned self-ligation problem as well. In...
For many applications it may be best to use the same ELISA protocol that was used to screen for MAbs during the isolation procedure because quite different MAbs may be selected depending on the ELISA procedure used (van Regenmortel, 1986). If highly concentrated preparations of MAbs are used ...
