introduzione
Blood is a valuable source of DNA for various clinical applications and research studies. Tuttavia, extracting DNA from blood samples presents several challenges:
Safety Concerns:
- Blood samples can harbor pathogens, posing a risk of infection to researchers and contaminating the lab environment.
- Traditional methods often involve hazardous chemicals like phenol-chloroform.
DNA Loss:
- Removing red blood cells, a common pre-treatment step can lead to the loss of desired DNA fractions like viral DNA, circulating DNA, and microbial DNA.
Impurities and Inhibitors:
- Blood contains various components that can interfere with downstream analyses like PCR and Southern blotting.
New Technology for Improved Blood DNA Extraction:
This product offers a novel approach to address these challenges:
- Safe and Efficient: The method eliminates the need for red blood cell removal, minimizing infectious waste and potential contamination.
- Comprehensive DNA Recovery: The protocol allows for the purification of total DNA, including genomic, mitochondrial, viral, and circulating DNA, providing a more complete picture for analysis.
- Broad Sample Compatibility: The method effectively purifies DNA from various blood components like whole blood (fresh or frozen), plasma, siero, cappotto buffy, e altro ancora.
- Downstream Applications: The extracted high-quality DNA is suitable for reliable PCR and Southern blotting analyses.
This innovative solution simplifies blood DNA extraction while ensuring safety, efficiency, and comprehensive DNA recovery. It represents a significant advancement for researchers working in various fields like diagnostics, forensics, and medical research.

Principio
Efficient DNA Purification with Silica Column Technology
This product utilizes a silica column-based method for rapid and efficient DNA purification. Here’s a breakdown of the process:
- Sample Lysis and Digestion: The sample is treated with a lysate solution and protease to break down cell membranes and degrade proteins. This releases DNA into the solution.
- Binding to Silica Membrane: The lysate containing the DNA is transferred to a silica column. The silica membrane in the column specifically binds DNA molecules through favorable interactions. Proteins and other impurities remain unbound.
- Washing: Wash buffers are passed through the column, removing unbound proteins and cellular debris that did not adhere to the silica membrane.
- Elution: Finalmente, a low-salt buffer (typically 10 mM Tris, pH 9.0, E 0.5 mM EDTA) is used to elute the purified DNA from the silica membrane. This buffer disrupts the interaction between DNA and the silica, allowing the purified DNA to be collected in a separate tube.
Vantaggi
- High-quality DNA – meets a variety of downstream applications, including PCR, qPCR, enzyme digestion, hybridization, eccetera.
- Veloce – without separation of leukocytes, organic extraction, or ethanol precipitation
- Simple – all nucleic acids can be obtained by direct digestion
- Wide applicability- handle a variety of liquid samples
