BlueGene Biotech NS0 Host Cell DNA Residue Detection Kit-100T

 N/S0 Host cell DNA Residue Detection Kit

 

The NS0 HCD Residue Detection Kit can be used for Quantitative analysis of DNA residue in recombinant protein expressed products, purified intermediate and finished products from host cells.

 

Specifications of NS0 Host Cell DNA Residue Detection Kit

Introduction

This kit adopts Taqman probe fluorescence qPCR method. The kit has the advantages of high specificity and sensitivity by using specific primers & probes, LOQ can reach 3fg/μL level. The preparation process of DNA Control is completely consistent with National Standard, therefore it has high purity and no protein and ion interference. DNA Control has been calibrated by National Standard to ensure the accuracy of the sample quantitative detection. The kit provides DNA Dilution Buffer, which enables good replicate parallelism in a single experiment and good reproducibility between multiple experiments.

The detection range of the standard curve mentioned above is suitable for most experiments and can be adjusted as needed

 

Criteria for Results

 

Standard Curve: R ²> 0.99; Amplification Efficiency: 90% ≤ Eff% ≤ 110%; Slope: -3.8~-3.1.

 

The recovery rate of spiked samples=(measured value of spiked samples - measured value of samples)/theoretical value of spiked samples * 100%, with a range of 50% -150%.

 

No Template Control (NTC): In the reaction system, replacing the target template with DNA Dilution Buffer while keeping other components unchanged, and the Ct value obtained should be 'Undetermined' or Ct value≥35.
