Virus-like particles (VLPs)-displayed antigens

LifeTein offers a series of Virus-like particles (VLPs)-displayed antigens. VLPs are nanoparticles derived from the capsid protein of a virus. Virus-like particles are used for antibody discovery for immunization and screening, affinity determination for ELISA, Surface Plasmon Resonance (SPR), in vivo pharmacokinetic analysis, CMC (Chemistry, Manufacturing, and Controls) method development, and CAR-T positive rate detection.

Other Proteins

We have developed a high-quality Laminin 521 product and Human Wnt Surrogate-Fc Fusion Protein that can be applied to scientific research and preclinical development. Our active Cas9 protein carries a nuclear localization signal (NLS) design. The in-house active CRISPR-Cas12a enzyme can recognize and cut DNA at a specific site different from the prototypical Cas9.
