Custom VLP Membrane Protein Expression Service

Sino Biological’s novel virus-like-particle (VLP) membrane protein expression technology


Membrane proteins play an important role in life activities. As important drug targets, membrane proteins are limited in application due to their low yield, difficult preparation, and poor stability. Sino Biological has built a VLP (virus-like particle) technology platform based on the HEK293 expression system, which can present the target membrane protein on the surface of VLP, making the detection much easier.

Currently, they have developed a full range of membrane proteins with good activity including GPRC5D, CLDN18.2, CLDN6 as catalog products. Sino Biological also provide customized services to expedite drug research and development process.
