What are the features of the DNA blood collection card? What are they mainly used for? Today disposable sampling swab company personnel to tell you, I hope to solve the questions in your mind.
(1) Features.
DNA collection blood card manufacturers, DNA oral cell collection card (standard indicator type) after special treatment. When the oral cell sample touches the collection card, the collection area changes from red to white, and the color change indication is sensitive. The location of the oral cell collection can be quickly determined for easy detection and recovery. Calibration. The collection card does not contain any chemical additives and other inhibitors that would interfere with PCR amplification. It can be used directly for PCR direct amplification without the need for water washing, purification and other steps. The success rate of PCR direct amplification is high. DNA samples from oral cells in the collection card are stable under appropriate conditions such as dryness and coolness and can be stored at room temperature for more than 15 years.
(2) Manufacturers of DNA collection blood cards, main uses.
It is suitable for the collection, preservation and examination of DNA oral samples from suspects, victims, parties and scenes.
(3) Technical parameters.
1) Filter paper thickness: 0.05cm ± 0.01cm
2) filter paper ash: 0.1% ± 0.001%
3)Assembly environment: clean room, 100,000, relative humidity 30%-50%
4)Total number of colonies: according to: GB / T14233.2-93 "medical infusion, blood transfusion, syringe test method part II: biological test method" test qualified.
5)Effective use area：Double ring. Each single ring ≧ 1.2cm × 1.2cm
6)Sterilization and antiseptic effect: after the nanosilver solution treatment, with antibacterial, antiseptic and bactericidal effect, can effectively ensure the stability of DNA samples in the preservation process.
7)DNA samples can be stored at room temperature for a long time without refrigeration, which greatly reduces the cost of DNA preservation.
8)The samples can be used for various target DNA tests and can be used multiple times for inspection and re-inspection.
9)No human source of contamination.
Each set includes: an oral cell collection card, a special bag for DNA database and a collection test.
