Summary A colorimetric method for the estimation of elastase activity has been presented. When dyed elastin substrate prepared from horse ligamentum nuchae is used, the pH optimum lies between 8.7 and 9.4, and the reaction velocity is linear only when less than 35% of the elastin is dissolved. When compared with the gravimetric and nitrogen procedures, this method has the advantages of rapidity and simplicity. 
Comparison of Different Assay Methods for Determination of Elastase Activity
Abstract Four different methods of pancreatic elastase (E. C. 3.4.21.11) assay have been compared: one use N-succinyl-(Ala)3-paranitroanilide as a substrate; the three others use elastin, modified orExpand
Elastolysis of insoluble elastin.
We developed an assay for measurement of elastolytic activity using insoluble 3H-labelled particulate elastin adherent to plastic that is capable of detecting 150 picograms of pancreatic elastase.Expand
Determination of elastolytic activity with 125-I and 131-I labelled elastin.
TLDR
A new method based on the use of 1311 and lZ5I labelled elastin is proposed for the detection and determination of low levels of elastolytic activity with greater sensitivity and its safe use in colored and turbid media. Expand
An evaluation of four methods for the measurement of elastase activity.
The precision of four different methods for the measurement of low levels of porcine pancreatic elastase was assessed using a synthetic substrate and by three other methods using the naturalExpand
Micromethods for the spectrophotometric determination of bacterial protease activities
Abstract Microassays for the spectrophotometric determination of bacterial proteases were developed using congo red elastin, a substrate specific for elastolytic activity, and hide powder azure, aExpand
Production and partial characterization of elastase of Bacillus subtilis isolated from the cervices of human females.
TLDR
The enzyme, purified by ammonium sulphate precipitation and Sephadex G-75 gel filtration, showed a molecular weight of 25,000 and activity between pH 6.0 and 9.5, with an optimum of 9.0 in Tris-maleate buffer. Expand
In situ histological evaluation of elastase activity.
TLDR
Microscopic examination within the zone of dense elastin is directed at determining the transition point above which the fibers have been visibly altered, but remain unchanged below, to provide a numerical value for elastase activity. Expand
Metabolism in marine flatfish--III. Measurement of elastase activity in the digestive tract of Dover sole (Solea solea L.).
TLDR
The properties of Dover soleElastase have been further investigated using chromatographic techniques which indicated that the main elastase activity has a molecular weight of approximately 19,500 and an isoelectric point in the region of pH 5.7. Expand
