The cost of making a Phycoerythrin conjugated tetramer is $800. The most expensive reagents are the biotin ligase (BirA from Avidity, LLC) and the PE-conjugated streptavidin (Prozyme). On occasion, it ...

TTR amyloidosis is caused by a number of point mutations in the TTR gene which increase the likelihood for the normal TTR tetramer protein to dissociate into monomers, which form amyloids.

SARS-CoV-2/COVID-19 Tetramer Reagents We produce a set of SARS-CoV-2/COVID ... We will perform the subcloning to the appropriate vector for protein expression and additional charges may apply. All ...

The choice of label is based upon the signal-to-noise ratio of the label, the capabilities of the flow cytometer that will be used for the assay, and the availability of other fluorescent antibodies ...

“It's the best ligand-protein binding pair in all of biology ... which interact very tightly to form the tetramer. Previous attempts to stabilize the dimer have involved engineering strategies ...

Figure 2: Cryo-EM reconstruction of the latrotoxin tetramer in a, top and b, side view. As with other pore-forming toxins, an initially soluble protein is converted into a membrane-inserted pore ...
