Northern blot probe design
WebNorthern blotting involves the use of electrophoresis to separate RNA samples by size, and detection with a hybridization probe complementary to part of or the entire target sequence. Strictly speaking, the term 'northern blot' refers specifically to the capillary transfer of RNA from the electrophoresis gel to the blotting membrane. Gene probes, cloned or PCR-amplified, and oligonucleotide probes can be random-primed labeled with radioactive isotopes and nonradioactive labels (e.g., DIG). Random-primed labeling of DNA fragments (double-or single-stranded DNA) was developed by Feinberg and Volgestein (8,9) as an alternative to … Ver mais A very robust method for labeling a gene probe with DIG uses PCR. The probe is PCRamplified using the appropriate set of primers and thermocycling parameters, however, the dNTP … Ver mais End labeling of probes for hybridization is mainly used to label oligonucleotide probes (for a review, see ref. 14). Roche Biochemicals (6) has developed three methods for labeling … Ver mais
