Background:

  • ADAMTS (a disintegrin and metalloproteinase with thrombospondin motifs) are a family of 19 secreted metalloproteinases.
  • Their roles in physiopathological conditions are significant but not fully understood.
  • Challenges exist in producing and purifying active recombinant ADAMTS enzymes for research.

Purpose of the Study:

  • To describe protocols, tips, and tricks for the production and purification of ADAMTS enzymes.

Cleavage and Blastulation01:33

Cleavage and Blastulation

After a large-single-celled zygote is produced via fertilization, the process of cleavage occurs while zygotes travel through the uterine tube. Cleavage is a mitotic cell division that does not result in growth. With each round of successive cell division, daughter cells get increasingly smaller.

A Fluorogenic Peptide Cleavage Assay to Screen the Proteolytic Activity of Proteases

This video demonstrates an assay to screen for the proteolytic activity of proteases using fluorogenic peptides. The protease recognizes its cleavage site on the peptide, cleaving it and separating the quencher from the fluorophore, enabling its fluorescence emission. The fluorescence signal is detected and analyzed to check for the cleavage efficiency of different peptide...
