Storage conditions
Only used for scientific research on sample collection, processing, and storage methods at 14 ℃ or -20 ℃
1. Serum: Use test tubes free of pyrogens and endotoxins, avoid any cell irritation during the operation, collect blood, centrifuge at 3000 rpm for 10 minutes, and quickly and carefully separate serum and red blood cells.
2. Plasma: anticoagulant with EDTA, citrate or heparin. Centrifuge at 3000 rpm for 30 minutes and collect the supernatant.
3. Cell supernatant: Centrifuge at 3000 rpm for 10 minutes to remove particles and polymers.
4. Tissue homogenate: Crush the tissue by adding an appropriate amount of physiological saline. Centrifuge at 3000 rpm for 10 minutes and collect the supernatant.
5. Storage: If the sample is not tested in a timely manner after collection, please divide it into batches according to a single dose, freeze it at -20 ℃, avoid repeated freezing and thawing, thaw it at room temperature, and ensure that the sample is evenly filled and thawed.

Features and Advantages
1. Specificity: All primers used in the product have undergone detailed bioinformatics analysis, and have been compared with TIANDZ and a large self built database to ensure that each primer used is a species or serotype specific gene sequence segment, which can achieve specific detection of bacterial species and serotypes with specificity.
2. Reproducibility: All products in this series have been validated by a large number of experimental strains, with a reproducibility of.
3. Sensitivity: This series of products can achieve highly sensitive detection of bacteria. When the concentration of bacteria in the sample reaches 103 cfu/ml, it can be directly detected without the need for tedious bacterial growth processes.
4. Practicality: The detection range is wide, covering 17 respiratory and intestinal pathogenic bacteria that pose a serious threat to human health. It can achieve rapid detection of clinical samples and other environmental samples, and the entire detection process takes 3-4 hours.
5. Advantage 1: Rich sequence resources. In addition to the sequences published by TIANDZ, the company has also deciphered a large number of bacterial strains, theoretically ensuring that the selected primers have good conservation and specificity.
Advantage 2: This series of test kits has undergone extensive conservative and specific experimental verification. With the company's abundant bacterial resources, each detection kit has undergone conservative verification of more than 20 standard and clinical strains, as well as specificity verification of more than 40 closely related standard and clinical strains, ensuring that there will be no false positive or false negative reporting results during use.


​
reaction conditions
It varies depending on the size of the amplification segment, reaction volume, and the use of amplification instruments.
◇ Number of cycles
Set 25-30 cycles based on the amount of template DNA and the size of the amplification segment.
If the number of cycles is too small and the amplification amount is insufficient; If there are too many cycles, Smear will occur.
Annex and Extension
The appropriate Anneal temperature is usually between 45 and 68 ℃ (preliminary experiments can be conducted at intervals of 2 ℃). In addition, due to its high activity between 60-68 ℃, the Anneal Extension temperature can be set within this temperature range for 2-step PCR. When the temperature of Anne Extension is 68 ℃, it can be set for approximately 30 seconds to 1 minute per kbp; When the temperature is set below 68 ℃, the time setting can be slightly longer. Usually, if the temperature of Anneal is too high, amplification products may not be obtained at times; When the temperature is too low, non-specific reactions are prone to occur. In addition, if the extension time is too short, amplification products may not be obtained or there may be some short non-specific products; When the extension time is too long, Smear will appear.
