Canvax is a leading manufacturer and supplier of the most innovative solutions, kits and R&D Reagents inside Molecular Biology fields. Since its foundation in 2001, Canvax offers reliable, cost-effective and easy-to-use innovative tools for research. Based in Córdoba (Spain), since its beginning it has focused on R&D of multiplex high throughput platforms (HTS) for Drug discovery and Diagnostic applied biosensors. Over a decade later, Canvax is a worldwide leading expert in GPCR expression in heterologous cells, with important patents and exclusive know-how. Canvax prides itself to be the first company to get an unprecedented milestone that could revolutionize the Diagnostics sector: Canvax established stable high-level expression of odour GPCRs into heterologous cell lines in 2014. This key milestone, that could be applied in diagnostic, perfume and cosmetic industry, are being employed to obtain a molecular nose, a sensitive and non-invasive diagnostic molecular device for early detection of cancer, as the nose of trained dogs do. Thanks to this project, Canvax was awarded, in 2013, with the largest Public & Private Contract for Pre competitive Technology Development in Spanish history.

Blood genomic DNA extraction - Precipitation
The most common organic extraction is the method using phenol-chloroform solution
Phenol extraction is a commonly used method for removing proteins from a DNA sample, e.g. to remove proteins from cell lysate during genomic DNA preparation.
Organic extraction involves the addition of and incubation in multiple different chemical solutions; including a lysis step, a phenol chloroform extraction, an ethanol precipitation, and washing steps.
Samples are homogenized in a phenol-containing solution and then centrifuged after chloroform addition. During centrifugation, the sample separates into three phases: an upper aqueous phase which contains DNA, an interface containing the proteins, and a lower organic phase containing RNA and lipids.
The advantage of the phenol-chloroform method is the simplicity of the protocol, the rapid denaturation of nucleases and the stabilization of nucleic acids. The main disadvantage is the use of toxic chemicals phenol and chloroform, and there is an increased risk of contamination due to transferring the DNA between multiple tubes.
