Single-step fusion-based affinity purification of proteins with pH-controllable linkers was carried out in a fluidic device. The linkers were previously derived from self-splicing protein elements called inteins. Two different linkers were generated to solve two distinct separation problems: one for rapid single-step affinity purification of a wide range of proteins, and the other specifically ...
Challenges in purification and subsequent functionalization of membrane proteins often complicate their biochemical and biophysical characterization. Purification of membrane proteins generally involves replacing the lipids surrounding the protein with detergent molecules, which can affect protein structure and function. Recently, it was shown that styrene-maleic acid copolymers (SMA) can disso...
Visualization systems for tracking proteins are standard experimental tools in most areas of biological research apart from protein purification. Here, we have sought to plug this gap by producing red and yellow visual tags using the heme-binding domain of mosquito cytochrome b5 and the flavin mononucleotide (FMN)-binding domain of human P450 reductase. Tests with colorless glutathione-S-transf...
Proteomic approaches require simple and efficient protein purification methodologies that are amenable to high throughput. Biotinylation is an attractive approach for protein complex purification due to the very high affinity of avidin/streptavidin for biotinylated templates. Here, we describe an approach for the single-step purification of transcription factor complex(es) based on specific in ...
In this work, we obtain a producer of the recombinant SARS-CoV-2 E protein and develop system for its expression purification in soluble form. ELISA confirmed antigenic properties. COVID-19 convalescents, level IgG against was significantly increased comparison with control group patients.
SDS-polyacrylamide gel electrophoresis (SDS-PAGE) transfer method was used for purification and enrichment of the protein from crude sample. Coomassie bluc/ZnSO4 stained protein band(s) containing intact polyacrylamide gel were loaded on to another polyacrylamide gel either alone or as pooled gel bands. Two/three bands were combined together and arranged tightly over one another, sealed with st...
Due to the high costs associated with purification of recombinant proteins the protocols need to be rationalized. For high-throughput efforts there is a demand for general methods that do not require target protein specific optimization . To achieve this, purification tags that genetically can be fused to the gene of interest are commonly used. The most widely used affinity handle is the hexa-h...
A new chemical affinity system is described for the purification of proteins. The Linx Affinity Purification System enables researchers to quickly and easily bind a protein ligand to a chromatographic matrix and use the resulting affinity resin to purify a second protein from crude mixtures. The entire process takes approximately 2 h.
