  • degrade
  • What you see are that (1) the more degrader molecule you add, the more BRD protein degradation you get, but only up to a saturation point, (2) BRD2 and BRD4 degrade much more quickly than BRD3 if you're using MZ1, but not if you're using dBET1, and (3) the time needed to reach maximum degradation varies quite a bit depending on the protein and degrader.

  • Molecular
  • Native PAGE preserves the original protein molecular structure, but it is a relatively more challenging and unstable method. (biopharminternational.com)
  • In Native Page (see Figure 1 ), the relative distance of protein bands depends on their molecular weights and isoelectric points, which makes it hard to perform meaningful calculations due to the inherent differences in isoelectric points among proteins. (biopharminternational.com)
  • However, introducing the SDS molecule, which uses a detergent with a strong electrical charge, negates the isoelectric point issue and allows a quantitative method to calculate both the molecular weight and protein volume. (biopharminternational.com)
  • In degradation studies, a combination of the two methods was used by using SDS-PAGE as a quantitative method to calculate the molecular weight and volume of residues, and by using Native PAGE to ascertain that the degradation of the protein was by the combination treatments rather than the SDS molecule.
