背景 :
Ephrin-A4 (EFNA4) is also known as EPH-related receptor tyrosine kinase ligand 4 (LERK4), EPLG4, which belongs to the ephrin family. EFNA4 contains one ephrin RBD (ephrin receptor-binding) domain. EFNA4 is cell surface GPI-bound ligand for Eph receptors, a family of receptor tyrosine kinases which are crucial for migration, repulsion and adhesion during neuronal, vascular and epithelial development. EFNA4 binds promiscuously Eph receptors residing on adjacent cells, leading to contact-dependent bidirectional signaling into neighboring cells. EFNA4 may play a role in the interaction between activated B-lymphocytes and dendritic cells in tonsils.

ACROBiosystems is a leading manufacturer of recombinant proteins and other critical reagents to support the development of target therapeutics, vaccines and diagnostic kits.

Our team has worked tirelessly since the genomic sequence of SARS-CoV-2 was first published, developing a serial of critical reagents to fight COVID-19. Our team has successfully developed a new neutralizing antibody titer serologic assay kit for COVID-19 vaccine evaluation (Cat.No.TAS-K022) which really showed excellent performance.

As the emerging variants may have impacted on the development of the COVID-19 epidemic, our team is also going full steam ahead on developing a collection of spike mutants for the emerging variants of SARS-COV-2. The reagents can be used to evaluate the efficacy of the antibodies and vaccination.

We have also developed an extensive collection of recombinant proteins to support the development for bispecific antibodies, antibody drug conjugates and cell therapies.
