If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.

Über diesen Artikel
Application
- für die Detektion der proteolytischen Aktivität mittels Casein-basiertem Protease-Assay
- zum Testen der extrazellulären proteolytischen Aktivität von Pilzstämmen
- für die Quantifizierung der mitochondrialen Proteaseaktivität
- zur Messung der Proteaseproduktion in Bodenlösung
Preparation Note
Die Trichloressigsäure-Komponente (TCA) wird als 6,1 N TCA-Lösung bereitgestellt. 0,6 N TCA-Lösungen können durch eine 10-fache Verdünnung des gewünschten T0699-Voluments mit ultrareinem Wasser hergestellt werden. Es ist nicht erforderlich, das Gesamtvolumen von T0699 für die sofortige Verwendung des Kits zu verdünnen.

How is shipping temperature determined? And how is it related to the product storage temperature?
1 answer-
Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf

Is this kit able to detect protease from Pseudomonas fluorescens in milk? How many determinations can be done with one kit?
1 answer-
This kit would not distinguish between protease from P. fluorescens and protease from any other microbial source or, for that matter, from trace mammalian protease activity that might be present in the milk. While there is nothing about milk that would preclude its analysis using this kit, without knowing the bacterial load and the expression level of the protease, it is not known if the kit could detect the protease levels in the milk. Each kit contains sufficient reagents for 200 assays, including blanks and controls.

Seeking clarity on step 7 on the procedure. Should the supernatant be collected? How should it be done without capturing any precipitate/pellet? This seems to be affecting themeasurements.
1 answer-
For kit PF0100, it's recommended to transfer the samples from the centrifuge to a secondary container before pipetting into the cuvette or well plate to ensure homogeneity and prevent false positive readouts during fluorescent detection.

If RIPA lysis buffer is used for cell lysis in cultured cells without isolating the mitochondria, will it have an impact on the protease detection when utilizing the PF0100-1KT Protease Fluorescent Detection Kit?
1 answer-
The QC tests for protease in the R0278 RIPA lysis buffer show no increase in background from the data, indicating no additional breakdown of the FITC-casein substrate when mixed with RIPA buffer. It is recommended that the use of R0278 or an equivalent, as this buffer is protease-free.

I want to use the protease fluorescent detection kit in cultured cells without isolating the mitochondria. If I use RIPA lysis buffer for cell lysis, will it affect the protease detection?
1 answer-
RIPA lysis buffer is compatible with this kit, provided that it is protease free. Please see the link below to review product R0278, a protease free RIPA buffer option:
