Summary:

 Purpose

Our Quick Step Bovine Matrix Metalloproteinase-9 (MMP-9)ELISA Kit is to assay MMP-9 levels in Bovine serum, plasma, culture media or any biological fluid.

 

Principle

This ELISA kit uses Sandwich-ELISA as the method. The Microelisa stripplate provided in this kit has been pre-coated with an antibody specific to MMP-9. Standards or samples are added to the appropriate Microelisa stripplate wells and combined to the specific antibody. Then a Horseradish Peroxidase (HRP)-conjugated antibody specific for MMP-9 is added to each Microelisa stripplate well and incubated. Free components are washed away. The TMB substrate solution is added to each well. Only those wells that contain MMP-9 and HRP conjugated MMP-9 antibody will appear blue in color and then turn yellow after the addition of the stop solution. The optical density (OD) is measured spectrophotomeMMP-9ally at a wavelength of 450 nm. The OD value is proportional to the concentration of MMP-9. You can calculate the concentration of MMP-9 in the samples by comparing the OD of the samples to the standard curve.

Typical Data

The standard curve of QS0334Bo is provided for demonstration only. A standard curve should be generated for each set of samples assayed.

S1	3600pg/ml	1.912	1.9075
		1.903
S2	2400pg/ml	1.388	1.3840
		1.380
S3	1200pg/ml	0.708	0.7100
		0.712
S4	600pg/ml	0.403	0.4000
		0.397
S5	300pg/ml	0.189	0.1960
		0.203
