Avance Biosciences, Inc. provides all necessary expertise for Southern or Northern blot projects from nucleotide extraction to probe design. We offer Southern blot analysis to support gene discovery and confirmation, gene mapping, evolution and development studies, diagnostics, and forensics tests. Transcript Analysis by Northern Blot service is offered to detect the presence of an expressed transcript containing a sequence of interest.
DNA will be extracted from testing samples followed by UV quantitation and electrophoresis analysis. After restriction digest with enzymes, DNA samples are separated by agarose gel electrophoresis and then transferred and UV cross-linked to a positive charged nylon membrane. Probe DNA will be prepared and labeled with either Chemiluminescent or 32P chemistry. After hybridization, the captured fragments will be visualized by exposure of X-Ray film.
Total RNA will be isolated from the test article (integrated cells) and untransfected cells. The total RNA (approximately 2 – 5 µg per sample) will be electrophoresed and transferred/cross-linked to positive-charged nylon membrane. The same probe designed for the Southern blots (if Southern blot analysis is performed) will be used for the Northern blots hybridization. Hybridized transcript(s) will be visualized by exposure of X-Ray film. After producing the autoradiogram, the size of the detected transcript(s) will be determined.
When you partner with Avance Biosciences, you gain a CRO partner that is creative, collaborative and dedicated to sound science with a focus on the regulatory requirements our partners require. Contact our technical staff to discuss how we can support you in your project!
