Overview Service Process Examples and Solutions Frequently Asked Questions

Overview

In vitro assays involve testing proteins in controlled environments, such as test tubes or microplates, to study their biochemical and biophysical properties. These assays can measure enzymatic activity, binding interactions, stability, and other functional characteristics. Our in vitro assay services utilize state-of-the-art technologies and methodologies to deliver high-quality, reproducible data tailored to your research needs.

In Vitro Assays for Protein Function Service usually use a series of technical methods, such as enzyme activity determination, immunoprecipitation, gel electrophoresis, protein structure analysis, etc. Specifically, this includes the following technical methods:

Enzyme activity measurement: Evaluate the function of a protein by measuring its enzyme activity. This usually involves reacting proteins with substrates and then measuring the production rate of the products.
Immunoprecipitation: By binding to specific antibodies, target proteins are precipitated to detect their function and interactions with other molecules.
gel electrophoresis: By placing proteins in gel for electrophoresis, proteins of different sizes and charges can be separated, so as to evaluate their structure and function.
Protein structure analysis: Analyze the structure of proteins through techniques such as X-ray crystallography and nuclear magnetic resonance to understand their function and activity.

Service Process

The process of conducting in vitro assays for protein function involves several critical and interrelated steps:

Project Consultation: Collaborating with researchers to define specific assay requirements, including the target protein, desired measurements, and intended application.
