CheKine™ Micro Soil Neutral Protease (S-NPT) Activity Assay Kit

Soil protease is involved in the transformation of amino acids, proteins and other organic compounds containing protein nitrogen in soil. Its hydrolysate is one of the nitrogen sources of higher plants. Soil neutral protease catalyzes protein hydrolysis in neutral environment, which is related to soil organic matter content, nitrogen and other soil properties. CheKineTM Micro Soli Neutral Protease (S-NPT) Activity Assay Kit can be used to detect biological samples such as soli. In the kit, under neutral conditions, casein can be hydrolyzed by soil neutral protease to produce tyrosine. In alkaline condition, tyrosine reduced phosphomolybdic acid compound to form tungsten blue, which has an absorbance peak at 680 nm.

Storage at 4°C and Keep from light immediately upon receipt. Kit has a storage time of 6 months from receipt. Refer to list of materials supplied for storage conditions of individual components.

• If not assayed immediately, samples can be stored at -80°C for one month.• It is recommended to perform several dilutions of your sample to ensure the readings are within the standard value range.• Fresh samples are necessary for good results. If don't perform the assay at the same time, it's better to complete the Sample Preparation step before storing the samples.
