Creative Diagnostics has developed a range of host cell DNA assay kits for use in specific cell line expression systems based on rapid qPCR technology, which can be used for highly sensitive, highly accurate detection and quantification of host cell DNA contamination. These residual DNA molecules present in the human body along with biological products can lead to increased risk of carcinogenesis, infection and immunomodulation. The World Health Organisation (WHO) and the European Union (EU) allow residual DNA levels of up to 10 ng/dose and the US Food and Drug Administration (FDA) allows residual DNA levels of up to 100 pg/dose. To meet these requirements, methods with high sensitivity and accuracy are needed to detect and quantify low levels of DNA.
The newly released Animal-Derived DNA Residue Assay Kits utilize advanced qPCR technology to provide rapid and reliable results. By targeting specific animal DNA sequences, these kits enable precise detection and quantification of even trace amounts of residual animal material, minimizing the safety risks of animal-derived components and safeguarding public health. These innovative Animal-Derived DNA Residue Assay Kits, such as the Porcine DNA Residue Assay Kit and the Bovine DNA Residue Assay Kit, are essential tools for ensuring the integrity of biological products such as therapeutic proteins, vaccines, and antibodies.
For example, the Bovine DNA Residue Assay Kit (Cat. No. DDNA-017) is a PCR-based fluorescence probe assay for the quantitative detection of bovine DNA residues in biological samples. Offering high sensitivity and specificity, the kit can rapidly detect bovine DNA at the femtogram level. It includes a bovine DNA quantitative reference standard and is paired with the Creative Diagnostics MagIso Animal-derived Biomaterials Residual DNA Extraction Kits (Magnetic Beads) for optimal sample preparation. This assay is ideal for the accurate measurement of bovine DNA residues in various biomaterials, such as membranes, patches, and decellularized matrices.
The ResDetFast Human DNA Residue Assay Kit (Cat. No. DDNAF-018) is a rapid and sensitive qPCR assay for the quantitative detection of residual human DNA in biological products. It employs PCR primers and probes targeting conserved human genome sequences and includes a ready-to-use human DNA reference standard. When combined with the Creative Diagnostics Nucleic Acid Extraction or Purification Kit, the assay can detect femtogram levels of human DNA in just 1.5 hours. This kit is specifically designed for the quantitative detection of human host cell DNA in intermediate, semi-finished, and finished biological products.
