Northern blotting

[¦nȯrth·ern ′bläd·iŋ]
(genetics)
Method of ribonucleic acid (RNA) detection and identification in which the intact RNA is separated by size via gel electrophoresis, transferred (blotted) onto nitrocellulose or nylon paper, and then hybridized with labeled DNA probes.

LPL mRNA levels were determined by Northern blotting and laser scanning of autoradiographs.
It is a more sensitive method to quantify gene expression than conventional methods used for mRNA evaluation, such as Northern blotting, dot-blot analysis, and the RNase protection assay.
The assay is a rapid (17) and sensitive method to quantify gene expression and requires smaller amounts of breast tissue than conventional methods, such as Northern blotting (18).
The purified RNA is of the highest integrity, and can be used in a number of downstream applications including Real-Time PCR, reverse transcription PCR, Northern blotting, RNase protection and primer extension, and expression array assays.
We isolated the full-length cDNA of porcine FoxO1 gene using RACE, confirmed by visual Northern blotting.

The protein and mRNA contents of UGT2B1 also were not detected in the fetal rat liver, but a developmental increase in newborn rat liver was detected by Western and Northern blotting analysis.
Neither genomic Southern blotting nor Northern blotting of tumor RNA can be performed successfully with the degraded nucleic acids obtained from fixed and embedded tissue specimens.
Ready-to-use SuperSignal(R) Substrates, which are designed for use with horseradish peroxidase-labeled (HRP) reporter molecules immobilized on membranes or on microplates, emit an intense, long duration signal when they come into contact with antigen during Western, Southern or Northern blotting or enzyme-linked immunosorbent assays.

Although duplicate performance of experiments may seem time consuming, our experience has shown that the extra effort expended at this stage is more than repaid by reducing unnecessary cloning, sequencing, and Northern blotting later in the process.
