      Product Detail  


    Brief Overview

    HMG (HMGB1) recombinant protein is lyophilized solid raw material expressed in Escherichia coli and purified via multi-step affinity chromatography, followed by 0.2μm sterile filtration and low-temperature vacuum freeze-drying. This item is solely supplied for closed in-vitro basic academic research of universities, biomedical research institutions and biotechnology R&D teams, covering chromatin regulatory mechanism research, intracellular signal pathway exploration, in-vitro immune cell model construction, nucleic acid-protein interaction test and biochemical mechanism analysis of multi-tissue slice co-culture. The finished product is uniform off-white lyophilized powder with complete and stable protein molecular conformation, delivering highly repeatable experimental data across batches and maintaining stable biological activity during long-term continuous cell strain passaging and organ slice incubation. Multiple vacuum-sealed neutral borosilicate glass vial specifications are available to match diverse laboratory testing plans: 5μg, 10μg, 50μg, 100μg, 500μg. Each production batch is equipped with complete technical archives including independent batch inspection reports and unified technical datasheets, merely for internal laboratory filing and academic reference.
    Core Laboratory Research Application & Functional Characteristics
    1. Strict Usage Restriction Statement

      This solid protein material is only suitable for isolated laboratory in-vitro cell cultivation and fundamental scientific research. It must never be applied to human oral intake, external coating, physical conditioning, any in-vivo animal intervention, clinical detection, cosmetic raw material processing or food additive preparation. All permitted laboratory research directions are listed below:

      In-vitro quantitative measurement of intracellular chromatin remodeling, DNA repair and gene transcription regulatory mechanisms

      Comparative cell model testing for regulatory mechanism of intracellular inflammatory enzyme gene expression under controlled in-vitro cultivation environments

      Observation testing of intracellular secondary messenger signal cascade changes triggered by protein supplementation

      Basic exploration of cellular detoxification metabolic mechanism and functional features of GST enzyme cofactor in liver cell line models

      Biochemical research projects on multi-substance metabolic axis feedback regulation and microenvironment characteristic analysis of multi-tissue co-culture systems

      Gradient comparison testing of somatic cell anti-oxidative damage activity variation under different protein additive concentrations

      Laboratory verification of correlation between intact full-length protein molecular structure and long-term anti-degradation stability inside cell culture medium

      Research on oxidative stress balance of aging cells and linked intracellular energy metabolism signal pathways

      Long-term cell incubation testing of metabolic signal regulation and cell activity maintenance in multi-type organ tissue co-culture systems

      Contrast testing of intracellular retention efficiency between complete HMG protein and hydrolyzed fragment derivatives inside standard cell culture medium

      Quantitative research on expression fluctuation of metabolism-associated transcription factors induced by protein supplementation in chemically damaged cell models
    2. Exclusive Research Advantages

      Dual Conserved Binding Domain Target Binding Feature

      The complete full-length amino acid chain carries two conserved functional binding domains, which can steadily bind target receptors distributed on cell membranes and participate in intracellular non-specific nucleic acid binding cycles inside experimental containers. It acts as standard reference substance for chromatin and immune pathway research, supplying low-interference, single-variable comparative data for protein-receptor interaction and cell metabolic signal research, and effectively eliminates multiple confounding interfering factors in parallel control cell groups.
    Superior Long-Term Structural Stability After Lyophilization

    Low-temperature vacuum dehydration locks intact linear polypeptide skeleton and dual functional binding domain conformation, preventing polypeptide chain hydrolysis, non-specific molecular aggregation during storage and cross-border transportation. The prokaryotically expressed amino acid chain can resist degradation by intracellular proteases, solving the defect of rapid biological activity loss of liquid medium samples, greatly lowering repeated reagent preparation workload for long-term laboratory inventory management and continuous cell passaging experiments, and supporting multi-day uninterrupted cell culture experimental schemes without frequent medium replenishment.
    Broad Compatibility With Conventional Mammalian Cell Culture Systems

    This lyophilized powder can be fully dissolved in laboratory dedicated bacteriostatic purified water and neutral PBS buffer solution with adjusted pH value. It matches conventional macrophages, fibroblasts, mesenchymal stem cells, liver precursor cells and multi-tissue slice testing systems, will not introduce foreign contaminants that disturb cell growth microenvironment, and will not trigger abnormal cytotoxic responses within standard research concentration ranges.
    Stable Concentration-Dependent Gradient Linear Responses

    Adjustable working concentrations fit customized experimental designs; multiple detection indicators including metabolic enzyme synthesis level, intracellular free radical content and cell proliferation ratio show stable linear changes along concentration gradients, facilitating quantitative data statistics and academic paper graph drafting for basic polypeptide redox signal research.
    Ultra-Low Background Interference For Biochemical Detection Analysis

    Multi-stage layered reversed-phase chromatographic purification removes residual truncated polypeptide fragments, incomplete synthesis by-products, free amino acid impurities and endotoxin contaminants in finished solid products. It will not generate extra noise signals for spectrophotometers, fluorescence detectors and cell proliferation colorimetric testing equipment, providing reliable, clear biochemical quantitative detection results and stable repeatability for cell antioxidant signal verification experiments.
    Consistent Batch Performance Across All Production Lots

    Integrated standardized production workflow including prokaryotic expression, C-terminal affinity tag purification, multi-step desalting and vacuum freeze-drying guarantees unified protein purity, binding domain integrity and signal regulatory performance of all batches. It avoids experimental result deviations caused by inconsistent raw material synthesis batches, supporting parallel control experiments and repeated result validation for laboratory teams researching cellular oxidative metabolism signals.

    Standard Step-by-Step Dissolving Operation Guidance

    Recommended Matching Solvent Medium: Laboratory dedicated bacteriostatic purified water / pH 7.2–8.0 neutral PBS buffer
    1. Slowly inject the prepared buffer medium along the inner wall of the glass vial to avoid violent foaming and polypeptide binding domain oxidative denaturation
    2. Fully tighten the vial cap, rotate and swirl gently in slow circular motions for 3–5 minutes until all lyophilized solid powder is completely dissolved (the recombinant protein carries slight hygroscopicity, slow and gentle dissolution is required to prevent incomplete solvation and structural damage)
    3. Do NOT violently agitate the container; intense stirring will trigger irreversible conformational damage of dual binding domains and permanent attenuation of stable receptor binding signal activity
