MHC (Major Histocompatibility Complex)

Peptide-ready Major Histocompatibility Complexes (MHCs) are a critical component of the adaptive immune system, responsible for presenting antigens to T-cells, which play a crucial role in immune responses. MHC molecules are highly polymorphic cell surface proteins found in vertebrates, including humans, and are encoded by a complex gene family. The related linear peptidic epitope sequences are: EVDPIGHLY, NTDNNLAVY, YTDNWLAVY, ALYVDSLFFL, CLGGLLTMV, ELAGIGILTV, FLLTRILTI, FMNKFIYEI, GLYDGMEHL, GVYDGREHTV, HMTEVVRHC, KLPQLCTEL, KLVVVGAGGV, KMVELVHFL, KVAELVHFL, KVLEHVVRV, LMLGEFLKL, NLVPMVATV, PLFQVPEPV, RMFPNAPYL, SLLMWITQC, SLLMWITQV, SLLQHLIGL, YLEPGPVTA, YMLDLQPET, FMNKFIYEI, VVGAVGVGK, SSCSSCPLTK, VVGADGVGK, VVVGAAGVGK, VVVGAVGVGK, AYACNTSTL, IMPKAGLLI, VYFFLPDHL, GADGVGKSAL, VMAPKTLVL, RIIPRHLQL, SIINFEKL, AMAPRTLLL, and NQKLIANQF.

LifeTein provides single-chain peptide-MHC monomers, biotinylated MHC monomers, tetramers, and biotinylated tetramers, MHC-I Virus-Like Particles, and multivalent fluorescent MHC-I Virus-Like Particles.Other catalog products include NY-ESO-1, KRAS, MAGE, GP100, AFP, LMP2, Survivin, HBV, HPV, WT-1, and P53. Our functional peptide-ready MHCs products are a ready-to-use loading system for loading neoantigen peptides to form a new complete MHC peptide complex.

Applications of peptide-ready MHCs:

  • Research: Peptide-MHC tetramers or multimers are widely used in immunological research to detect and characterize antigen-specific T-cells. These reagents enable the precise identification and quantification of T-cells recognizing specific peptide antigens.
  • Vaccine development: Understanding the peptide epitopes presented by MHC molecules is crucial for designing vaccines that can elicit effective T-cell responses against pathogens or cancer cells.
  • Immunotherapy: Peptide-based immunotherapies, such as peptide vaccines or adoptive T-cell therapy, utilize knowledge of peptide-MHC interactions to target specific antigens in cancer treatment and infectious disease control.

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.
