Protein Microarray Service

Introduction

Microarray technology is to perform thousands of detections on a miniaturized device and was first proposed by Roger Ekins in 1989. This concept was first successfully transformed into DNA microarray technology, which can measure the mRNA expression levels of thousands of genes in parallel. However, DNA microarray technology has unavoidable limitations because the mRNA profile is not always correlated with protein expression. Since protein is the major driving force of almost all cellular processes, protein microarrays have been developed as a high-throughput tool for research in various fields.

Protein microarrays can be divided into two classes, analytical and functional, which have the characteristics of high sensitivity and good reproducibility. Unlike antibody arrays (analytical microarrays), functional protein microarrays are made by spotting all proteins encoded by an organism, so they can be used to study protein functions, including protein-other molecule interactions, enzyme-substrate relationship, biochemical activities, and immune responses, etc.

Services

The protein microarray platform Creative Proteomics sets up is jointly responsible by experienced protein analysts and experts. The platform is updated on time and upgraded regularly to provide customers with first-class, high-quality protein-related analysis services. There are still many challenges in the process of protein microarray services, especially in the production of proteins in a high-throughput fashion. The key points of our services include but are not limited to the following aspects:

• Protein production: a large amount of highly purified proteins
• Surface chemistry: immobilize proteins and preserve their three-dimensional conformation, providing many different characteristics of surfaces and immobilization methods
• Detection: label dependent and label free, and we also provide a variety of other technologies such as atomic force microscopy (AFM) and MALDI-TOF MS for technological expansion.

Customers can choose different technology platforms according to project requirements, or contact us directly for consultation, and our expert team will provide you with customized experimental procedures.
