    製品説明

    体外実験

    Guide (Following is our recommended protocol. This protocol only provides a guideline, and should be modified according to your specific needs).
    1. Buffer Exchange: Ensure the protein is in an amine-free buffer (e.g., PBS, 100 mM sodium phosphate, 150 mM NaCl) at pH 7.2-7.5. Avoid Tris or glycine.
    2. Reagent Prep: Equilibrate the NHS-Biotin vial to room temperature before opening to avoid condensation. Dissolve the reagent in high-quality anhydrous DMSO or DMF immediately before use.
    3. Reaction Ratio: Use a 12-20 fold molar excess of biotin reagent for protein concentrations of 2-10 mg/mL.
    4. Incubation: Incubate for 30-60 minutes at room temperature, or 2 hours at 4°C.
    5. Purification: Remove unreacted biotin using desalting columns (e.g., Sephadex G-25) or dialysis.
    6. Verification: Estimate incorporation using the HABA assay, where biotin displaces HABA from avidin, decreasing absorbance at 500nm.
    Note:
    1. Sulfo-NHS vs. NHS: Sulfo-NHS-Biotin is water-soluble and ideal for aqueous reactions, while NHS-Biotin requires organic solvent dissolution first.
    2. Moisture Sensitivity: NHS reagents are highly moisture-sensitive; store desiccated at ?20°C (or 4°C for some LC-NHS) and protect from humidity.

    MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

    Help & FAQs
    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
