产品描述（Product Details）
E1A resDNA Quantitation Kit is designed for quantitative detection of residual E1A DNA in biopharmaceutical productions (cells, viruses, etc.). Based on real-time quantitative PCR (qPCR) method, this kit makes detection the residual DNA rapid and reliable. The lower limit of quantitation is 40 copies/µL. All procedures are typically in less than 4 hours.
Use the kit after you extract residual DNA from test samples. For achieving the better DNA recovery, it is recommended to use the resDetect™ resDNA Sample Preparation Kit (Magnetic Beads) (Cat. No. OPA-R005) in combination.
产品特性（Features）
- High sensitivity for optimal product safety: LLOQ (40 copies/µL) for detection of residue DNA
- High specificity: No cross-reactivity with unrelated DNA
- Validation: ICH Q2(R2) as validation of analytical procedures
- High-quality: This kit is manufactured in GMP facility and alignment with the ISO 13485 standard.
应用说明（Application）
The kit is used for quantitative detection of residual E1A DNA in biopharmaceutical production.
For use in quality control/manufacturing process only.
It is for research use only.
技术参数（Technical Specifications）
使用提示（Attention）
If your experimental process requires sample preparation, please purchase and conduct the experiment using the sample preparation kits recommended in the table to ensure that the buffers used in both the sample preparation and resDNA detection are consistent.

Please refer to DS document for the assay protocol.
Figure 1. High sensitivity and broad dynamic range using the E1A resDNA Quantitative Kit. (A) Typical analysis results obtained with Standard 1 (4×10⁶ copies/µL) to 6 (4×10 copies/µL). (B) The standard curve of the 10-fold dilution series. PCR efficiency should be 90-110%.
To evaluate the specificity of assay using E1A resDNA Quantitation Kit, no template samples spiked with unrelated DNA were tested. Results shown in the following Table. Unrelated DNA (E. coli, CHO, Vero, and Pichia yeast) were not detected in assay, and the value of MDCK was outside the range of standard curve (4×10⁶ copies/µL to 4×10 copies/µL).
To evaluate the recovery of assay using E1A resDNA Quantitation Kit, three different concentrations of DNA samples were tested. Results shown in the following Table. All samples had recoveries between 95%-104%.
