General description

BSA is a single polypeptide chain consisting of about 583 amino acid residues and no carbohydrates. At pH 5-7 it contains 17 intrachain disulfide bridges and 1 sulfhydryl group.

Application

Bovine serum albumin is broadly used as an additive to cell culture media, especially serum-free media. It provides a range of benefits including protection from oxidative damage and stabilization of other media components such as fatty acids and pyridoxal.

SIRT3 is a nicotinamide adenine dinucleotide (NAD+)-dependent mitochondrial protein deacetylase purported to influence metabolism through post-translational modification of metabolic enzymes. Fuel-stimulated insulin secretion, which involves mitochondrial metabolism, could be susceptible to SIRT3-mediated effects. We used CRISPR/Cas9 technology to manipulate SIRT3 expression in...

Homogeneous functional assays that utilize competition binding technology are widely used for determining pharmacological properties such as intrinsic activity and potency. One example is time-resolved fluorescence resonance energy transfer (TR-FRET) 3',5'-cyclic adenosine monophosphate (cAMP) assays, where labeled cAMP (tracer) and...

The developmental biology of neural crest cells in humans remains unexplored due to technical and ethical challenges. The use of pluripotent stem cells to model human neural crest development has gained momentum. We recently introduced a rapid chemically defined approach...

Genome-wide association studies have associated thousands of genetic variants with complex traits and diseases, but pinpointing the causal variant(s) among those in tight linkage disequilibrium with each associated variant remains a major challenge. Here, we use seven experimental assays to...

We evaluated the use of gold nanoparticles (AuNPs) platform in a homogenous assay for a potency measurement of a therapeutic monoclonal antibody (mAb). The recombinant human ligand protein to the therapeutic mAb was immobilized on AuNPs via functionalized self-assembled monolayers....
