The spike (S) proteins of SARS-CoV-2 that mediate membrane fusion and host cell entry, contain several host-derived sugars, so called glycans. These glycoproteins provide fundamental features of viral biology, as they play key roles in protein folding and immune evasion. Watanabe and colleagues could reveal the glycan structures of a recombinant SARS-CoV-2 S protein. The researchers expressed Twin-Strep-tagged versions of the SARS-CoV-2 S protein in HEK cells and purified them from cell supernatants using Strep-Tactin®. Then they combined mass spectrometric and cryo-EM analyses to determine how the glycans cover distinct regions of the virus spike surface. With this site-specific glycan signature of the SARS-CoV-2 spike, the research team improved the understanding of viral biology with major implications for vaccine development.

Read how Wrobel et al. compare the spike glycoproteins of SARS-CoV-2 and closely related bat virus RaTG13 to uncover the virus emergence. Here, our protein purification products were exploited to optimize yield and purity by pretreatment of the expression culture with BioLock Biotin blocking solution before binding of the Twin-Strep-tag® fusion proteins to Strep-Tactin®XT and elution with with Buffer BXT.

See how Barinka et al. used a variety of our products: For protein purification they utilized our Strep-Tactin® Sepharose® columns and eluted their protein by addition of our desthiobiotin. Strep-Tactin® AP was deployed in ELISA screening to identify Anticalin candidates targeting the prostate-specific membrane antigen. For both immunofluorescence microscopy and analysis by flow cytometry, cells were immobilized for staining with our StrepMAB-Immo as primary antibody.

To access the feasibility of amber codon suppression for large and complex multidomain proteins, Heil et al. purified a Strep-tagged fusion protein with the aid of our Strep-Tactin® column and afterwards utilized our StrepMAB-Classic antibody as primary antibody for a quantitative western blot to read out incorporation efficiency of non-canonical amino acids.

Röhlen and colleagues present insights in the field of biosensor systems for both tricarboxylic acids as well as organic and volatile fatty acids. The researchers for instance worked on a hybrid biosensor system based on a bi-enzymatic detection principle. For expression of the proteins of choice, first our pENTRY vector was used and sub-cloned into pASG-IBA5 carrying either a C- or N-terminal Strep-tag®II. Following expression, our Strep-Tactin® MacroPrep® resin was used for protein purification exploiting the mild elution with desthiobiotin.
