背景信息

MHT1 recombinant protein is a biologically engineered molecule designed for research and therapeutic applications, particularly in oncology and immunology. Derived from human genetic sequences, MHT1 is typically expressed in mammalian cell systems (e.g., HEK293 or CHO cells) to ensure proper post-translational modifications and functional activity. This protein often serves as a critical component in studies exploring tumor microenvironment interactions, immune checkpoint regulation, or targeted cancer therapies.

Structurally, MHT1 contains functional domains that enable specific binding to cell surface receptors involved in immune modulation, such as PD-1/PD-L1 axis components or CTLA-4 pathways. Its recombinant form frequently incorporates fusion elements like Fc regions from human IgG to enhance stability and prolong serum half-life in experimental models. Production involves advanced purification techniques including affinity chromatography (e.g., Protein A/G) followed by rigorous quality assessments (SDS-PAGE, Western blot, endotoxin testing).

Current research utilizes MHT1 to develop bispecific antibodies, CAR-T cell therapies, and diagnostic tools for cancer biomarker detection. Its therapeutic potential lies in blocking immunosuppressive signals in tumor microenvironments or enhancing immune cell activation. Recent studies (2020-2023) highlight its role in overcoming treatment resistance in non-small cell lung cancer and melanoma. Commercial versions are often lyophilized for long-term storage, with activity typically measured through ELISA-based bioassays or flow cytometry binding assays. Ongoing optimization focuses on improving binding affinity (KD values in low nM range) and reducing immunogenicity for clinical translation.
