Serine Protease Zymography: Low-Cost, Rapid, and Highly Sensitive RAMA Casein Zymography
2017To detect serine protease activity by zymography, casein and CBB stain have been used as a substrate and a detection procedure, respectively. Casein zymography has been using substrate concentration at 1 mg/mL and employing conventional CBB stain. Although ordinary casein zymography provides reproducible results, it has several disadvantages including ...

Cysteine Protease Zymography: Brief Review
2017Cysteine proteases play multiple roles in basically all aspects of physiology and development. In plants, they are involved in growth and development and in accumulation and mobilization of storage proteins. Furthermore, they are engaged in signalling pathways and in the response to biotic and abiotic stresses.

Zymography: Unveiling Matrix Metalloproteinase Dynamics
Zymography is a laboratory technique used to study the activity of enzymes, particularly proteases and glycosidases, in biological samples. It involves the separation of enzymatic proteins by gel electrophoresis under non-denaturing conditions, followed by their renaturation and incubation with specific substrates that mimic natural substrates.Qinghe, Meng, Adam, Novak, Erin, Rayhill

Zymography with Caseogram Prints: Quantification of Pepsinogen
Analytical Biochemistry, 2001In caseogram prints, a type of zymogram which is designed for the detection of acid proteases, enzyme activity is detected in an overlay gel of agarose containing skim milk. The use of this technique for protease quantification was investigated in this study using pepsinogen as an example protease.

Calpain Zymography: General Methodology and Protocol
2017Casein zymography has become one of the gold standard assays for monitoring mammalian calcium-activated proteases (calpains) in purified enzyme, cell, or tissue samples. This calpain zymography method takes advantages of (1) casein is an excellent substrate for major isoforms of calpains (Calpain-1, 2 and 3), (2) the embedded casein is digested into ...

Recent Updates on Protease Zymography
Proteases, also known as peptidases or proteinases, are enzymes that break down peptide bonds of proteins. It is essential for number of physiological processes like digestion, immune response, blood clotting, and cell regulation. Different versions of the same protease enzyme, or isoforms, result from post-translational modifications, alternative ...Abinaya, Kanagaraja, Raman, Pachaiappan

Application of Gelatin Zymography in Nanotoxicity Research
2018Gelatin zymography is a relatively simple, inexpensive, and powerful technique to detect proteolytic enzymes capable of degrading gelatin from various biological sources. It has been used particularly to detect the two members of the matrix metalloproteinase family, MMP-2 (gelatinase A) and MMP-9 (gelatinase B), due to their potent gelatin-degrading ...

Detection and Quantitation of Matrix Metalloproteases by Zymography
2003Matrix metalloproteases (MMPs) are a family of structurally and functionally related endopeptidases. They have in common a zinc ion at the active site and are released as an inactive proform (zymogen). Proteolytic activation enables MMPs to degrade components of the extracellular matrix such as collagens, fibronectin, and laminin [for review see (1-4)].

Cell In Situ Zymography: Imaging Enzyme–Substrate Interactions
2017Zymography has long been used for the detection of substrate-specific enzyme activity. In situ zymography (ISZ), an adaptation from the conventional substrate zymography, is a widely employed technique useful for the detection, localization, and estimation of enzyme-substrate interactions in tissues. Here, we describe a protocol to detect 'in position'

Electrophoretic Zymography of Protease Using Azocasein
Zymography is an electrophoretic technique used to demonstrate enzyme activity during separation in polyacrylamide gels under nonreducing conditions. This kind of analysis can be used in association with electrophoresis (SDS-PAGE) to show which protein is correlated with a given activity. Proteases are the most used enzymes for this technique since theCarvalho-Silva, Jônatas +3 more
