  • Product Details
    Pichia pastoris resDNA Quantitation Kit is designed for quantitative detection of residual Pichia pastoris DNA in biopharmaceuticals (Antibodies, Vaccines, etc.). Based on real-time quantitative PCR (qPCR) method, this kit makes the detection of the residual DNA from Pichia pastoris rapid and reliable. The lower limit of quantitation is 3 fg/µL. All procedures are typically in less than 4 hours.

    Use the kit after you extract host cell DNA from test samples. To achieve the best performances, resDNA Sample Preparation Kit Ⅱ(Magnetic Beads) (Cat. No. OPA-R024) is recommended for DNA extraction.

  • Features
    1. High sensitivity for optimal product safety: LLOD (1 fg/µL) for detection of residue host cell DNA
    2. High specificity: No cross-reactivity with unrelated DNA
    3. Validation: ICH Q2(R2) as validation of analytical procedures
    4. High-quality: This kit is manufactured in GMP-like facility and alignment with the ISO 13485 standard.
  • Application

    The kit is used for quantitative detection of residual Pichia pastoris DNA in biopharmaceuticals.

    For use in quality control/manufacturing process only.

    It is for research use only.

  • Background
    Residual host cell DNA refers to fragments of DNA from the host organism that are left behind after a biological process such as the production of a biopharmaceutical product or the cultivation of a cell line. This residual DNA can potentially contaminate the final product and affect its safety and efficacy. In the context of biopharmaceutical production, regulatory agencies such as the FDA and EMA have set limits on the amount of residual host cell DNA that is acceptable in a final product. These limits vary depending on the type of product and the route of administration, and residue host cell DNA quantitation kits are designed to ensure that the final product is safe for human use.
