Meat discriminator

1、Meat discriminator Brief Introduction:

Meat discriminator uses fluorescent quantitative PCR technology to quickly identify DNA information in meat, so as to accurately judge its type and source.Meat discriminator is an efficient and convenient food testing device designed specifically for identifying the authenticity of meat. It can detect various animal-derived components, including pork, beef, lamb, horse meat, donkey meat, duck meat, and chicken. It can quickly and accurately detect DNA components in meat and meat-derived samples, ensuring the authenticity and reliability of the meat consumed. Its high sensitivity and low error rate guarantee the accuracy of the test results, providing professional testing services for various testing institutions.

2、Meat discriminator System Components

Meat discriminator consists of a four-channel, 32-well fluorescence quantitative PCR instrument and a portable accessory case.

3、Meat discriminator Working Principle:

Meat discriminator detects through real-time quantitative PCR technology, utilizing specific primers and probes to amplify and detect DNA in meat samples.

The detailed working steps are as follows:

1. Sample Preparation: The meat sample is homogenized, and DNA is extracted.

2. PCR Reaction: Specific primers, probes, and sample DNA are added to a reaction tube and placed in a detection instrument for PCR amplification.

3. Real-time Detection: During PCR amplification, the instrument monitors DNA amplification in real time through fluorescence signals, generating an amplification curve.

4. Data Analysis: Based on the fluorescence signal intensity and amplification curve, it is determined whether the sample contains the specific DNA sequence, thus determining the authenticity of the meat.

4、Meat discriminator Technical Specifications

1. Features a high-grade aluminum alloy sample holder with excellent thermal conductivity, corrosion resistance, and oxidation resistance, along with Peltier heating and temperature control, and a comprehensive sealing design. Neither sample solution nor condensation will leak into the Peltier temperature control element or other electronic components below the sample holder, effectively extending the instrument's lifespan.

2. Utilizes a high-precision PT1000 temperature sensor, achieving a temperature control accuracy of 0.01℃, ensuring precise temperature control.

3. Sample throughput: 0.2ml single tube, 0.2ml 8-tube strip.

4. Open reagent and consumable system: Compatible with reagents from any brand, suitable for standard 8-tube strips or 0.2ml PCR single tubes.

5. Employs four high-intensity, broad-spectrum, long-life LED solid-state light sources (blue, green, red, and yellow), ensuring strong light intensity across the entire spectral detection range, improving detection sensitivity.  These LEDs generate no heat, have a long lifespan, and are maintenance-free for life.

6. High-sensitivity detector: Uses a high-sensitivity photomultiplier tube imported from Japan for higher detection sensitivity.

7. No optical path correction required: The scanning system ensures that the signal excitation and detection optical paths are completely consistent for each well, eliminating the need for optical path correction. This frees up a channel for correction, enabling true four-channel gene detection. ★

8. Number of channels: 4 channels.

9. Channel crosstalk: Uses high-precision narrow-band filters to greatly reduce channel crosstalk, and the software can also correct crosstalk parameters. 10. Detection Sensitivity: Capable of detecting single-copy DNA templates and clearly distinguishing between 1000 and 2000 copies of plasmid DNA.

11. Linear Detection Range: 10 orders of magnitude ★

12. Supports common fluorescent dyes and probe detection methods, such as SYBR Green I, Eva Green, Taqman, FRET, Molecular Beacons, Scorpions, Amplifluor, etc.

13. Module Temperature Range: 4-99℃

14. Control Mode: Built-in PCR operating system on the system screen or Windows computer ★

15. Interface: USB connection to computer

16. Operating Noise: Silent technology, maximum operating noise does not exceed 60dB during operation.

17. Operating and Analysis Software

17.1 Allows defining sample wells after running the program, saving experimental time.

17.2 Allows opening other experimental data results for viewing and analysis simultaneously while running the program.

17.3 The software automatically calculates the baseline range and sets the threshold line, providing users with reliable and accurate data results.

17.4 Experimental program settings and detection results can be directly printed as an experimental report, supporting export in multiple file formats and data styles such as XLS, CSV, and WORD ★

17.5 Results from the same batch of experiments can be grouped for independent data analysis, with up to 4 groups possible.

17.6 Provides both Chinese and English software interfaces. ★

17.7 The software can be installed on multiple computers without limitation, requiring no payment for usage rights, and offers free lifetime upgrades. ★
