General description
HRV-3C protease from human rhinovirus type 14 is a protease that specifically cleaves within an eight-residue recognition sequence.This sequence is: Leu-Glu-Val-Leu-Phe-Gln-Gly-Pro.Proteolytic cleavage occurs between the Gln and Gly residues. The HRV-3C protease is useful for cleaving recombinant proteins that are expressed as fusion proteins with this sequence between the carrier domain and the protein of interest.
This biotinylated HRV-3C protease is intended for on-column cleavage of fusion proteins with an HRV-3C cleavage site. It specifically cleaves the protein of interest from a column-bound fusion protein, leaving the fusion domain or tag bound to the affinity column (e.g. Ni-NTA column) and eluting only the protein of interest. This method is advantageous over post-elution cleavage for several reasons:
After cleavage, the protease can be removed with any avidin-conjugated or streptavidin-conjugated beads. This product has been enzymatically biotinylated with no effect on its proteolytic activity. It has no additional protein purification tags. The product is supplied in aqueous buffer (0.8–1.2 mg/mL) with 20 mM Trizma®-HCl, pH 8.0, 200 mM NaCl, 1 mM TCEP, and 50% (v/v) glycerol.

It specifically cleaves the protein of interest from a column-bound fusion protein, leaving the fusion domain or tag bound to the affinity column (e.g. Ni-NTA column) and eluting only the protein of interest. This method is advantageous over post-elution cleavage for several reasons:
- It eliminates most impurities normally associated with purification on Ni-chelating columns.
- It allows gentler elution conditions, with added flexibility in the elution buffer composition. This can mitigate protein aggregation and inactivation.

The 3-chymotrypsin-like cysteine protease (3CLpro) of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is considered a major target for the discovery of direct antiviral agents. We previously reported the evaluation of SARS-CoV-2 3CLpro inhibitors in a novel self-assembled monolayer desorption

SPTBN1 encodes βII-spectrin, the ubiquitously expressed β-spectrin that forms micrometer-scale networks associated with plasma membranes. Mice deficient in neuronal βII-spectrin have defects in cortical organization, developmental delay and behavioral deficiencies. These phenotypes, while less severe, are observed in haploinsufficient animals

The predominant approach for antibody generation remains animal immunization, which can yield exceptionally selective and potent antibody clones owing to the powerful evolutionary process of somatic hypermutation. However, animal immunization is inherently slow, not always accessible and poorly compatible with
