Purified Recombinant Proteins

Our proprietary purification processes and buffer formulations do not denature our proteins. They are easily conjugated, and our lyophilised proteins exhibit facile reconstitution.

Our SARS-CoV-2 recombinant proteins include N-terminal HIS-tagged Nucleocapsid Protein and N-terminal HIS-tagged Spike Receptor Binding Domain (RBD).

Our HIV-1 recombinant proteins include N-terminal HIS-tagged gp120 (expressed in HEK293 cells).  We also manufacture HIV-1 gp41, p24, HIV-1 Group O Variant gp41 and HIV-2 gp36 with N-terminal HIS-tags (expressed in E.coli).

HIV-1 gp41 (Ectodomain Subtype B)

HIV-1 gp41 (Group O Variant)

HIV-1 p24 (Subtype C Clone)

HIV-2 gp36 (Ectodomain)

HIV-1 gp120 (Subtype B Clone)

Our Treponema pallidum recombinant proteins include N-terminal His-tagged TmpA, TpN17 and TpN47 (expressed in E.coli)

Our Hepatitis C recombinant proteins include N-terminal His-tagged Core and NS3 (expressed in E.coli)

Our Dengue Fever Virus recombinant proteins include N-terminal His-tagged DIII Envelope proteins for all four subtypes (expressed in E.coli)

Our Salmonella typhi recombinant proteins include N-terminal His-tagged Outer Membrane Protein (OMP) and Haemolysin E (expressed in E.coli)

Our Zika Virus recombinant proteins include N-terminal His-tagged DIII Envelope protein (expressed in E.coli)

Recombinant Proteins Introduction

HIGHLY PURIFIED RECOMBINANT PROTEINS ARE USED IN THE MANUFACTURE OF DIAGNOSTIC TEST KITS.

Antigens

Our highly purified recombinant proteins are delivered to you in gentle, non-denaturing buffers, specifically formulated for ease of conjugation and efficient immobilization on a range of matrices (eg nitrocellulose, colloid gold, latex, cellulose nanoparticles).

 

Proprietary buffer formulations maintain our proteins in highly stable, native conformations resulting in exceptionally high specific activities that can be used at very low concentrations - ultimately resulting in significant cost savings to you the manufacturer.

 

With a comprehensive support service to assist you when you use our products, we can save you time and money by accelerating the assay feasability and development cycle.

BOTH INTERNAL AND INDEPENDENT EVALUATIONS HAVE SHOWN THAT OUR PROTEINS OUT-PERFORM THOSE OF LEADING MANUFACTURERS.
