Matrix metalloproteinases (MMPs) are zinc-dependent enzymes capable of breaking down all extracellular matrix (ECM) components. The gelatinases are a subgroup of MMPs which have two members: gelatinase A (MMP-2) and gelatinase B (MMP-9). They are highly efficient in breaking down denatured collagen I or gelatin. This ability of gelatinases has led to the development of a technique called gelatin zymography. This technique provides a simple, sensitive, and robust way to detect gelatinolytic activity in biological samples. This chapter provides a detailed protocol on how to implement the gelatin zymography and analyze gelatinases in biological samples using this technique.

摘要

Matrix metalloproteinases (MMPs) are zinc-dependent enzymes capable of breaking down all extracellular matrix (ECM) components. The gelatinases are a subgroup of MMPs which have two members: gelatinase A (MMP-2) and gelatinase B (MMP-9). They are highly efficient in breaking down denatured collagen I or gelatin. This ability of gelatinases has led to the development of a technique called gelatin zymography. This technique provides a simple, sensitive, and robust way to detect gelatinolytic activity in biological samples. This chapter provides a detailed protocol on how to implement the gelatin zymography and analyze gelatinases in biological samples using this technique.
