FAQ's

Find answers to frequently asked questions about our products and services by browsing the list below. If you need further assistance, please do not hesitate to contact our technical support team.

How much enzyme should I use for my assay?

An enzyme titration curve and calculated specific activity are included in the data sheet of each active enzyme. We recommend that researchers perform a serial dilution of an enzyme product to determine the optimal amount to use in their assay systems.

How do you calculate an enzyme's purity?

For all our products, we run an SDS-PAGE gel with a titration of the enzyme and perform densitometry measurements to determine purity.

How are your enzymes activated?

Our active enzymes are activated using specific protocols during the expression and production process to achieve optimal post-translational modification and in vitro activity. The treatment methods may vary for different enzymes, depending on their functional roles.

Why are some of your recombinant proteins expressed in E.coli cells, while others in Sf9 insect cells?

SignalChem Diagnostics carefully selects the expression system, either E.coli or Sf9 insect cells, based on the function and application of each product

Are your enzymes suitable for crystallography studies?

SignalChem’s active enzymes are validated for in vitro activity assays. We offer a wide range of custom services, including additional purification steps, buffer exchange, and tag modification, to fulfill the requirements for other applications such as protein crystallography. Please contact us for more information about this service.
