Which membrane is used in northern blotting?

nylon membrane
A nylon membrane with a positive charge is the most effective for use in northern blotting since the negatively charged nucleic acids have a high affinity for them.

Which paper is used in northern blotting?

The RNA is transfered to a sheet of special blotting paper called nitrocellulose, though other types of paper, or membranes, can be used. The RNA molecules retain the same pattern of separation they had on the gel. The blot is incubated with a probe which is single-stranded DNA.

Why is a nylon membrane used to blot the DNA?

In the original protocol nitrocellulose membrane have been used for the blotting in case of Southern blot but in recent times nylon membranes have been implemented for the blotting process due to their ability to bind more amount of DNA efficiently which allows the Southern blot to be carried out with less amount of …

What do you need for northern blot?

The steps involved in Northern analysis include:

  1. RNA isolation (total or poly(A) RNA)
  2. Probe generation.
  3. Denaturing agarose gel electrophoresis.
  4. Transfer to solid support and immobilization.
  5. Prehybridization and hybridization with probe.
  6. Washing.
  7. Detection.
  8. Stripping and reprobing (optional)

What kind of membrane is used for Northern blot?

Capillary blotting system setup for the transfer of RNA from an electrophoresis gel to a blotting membrane. A nylon membrane with a positive charge is the most effective for use in northern blotting since the negatively charged nucleic acids have a high affinity for them.

How is northern blotting used in RNA analysis?

Northern blotting technique Northern blotting is the capillary transfer of resolved RNA fragments from the denaturing agarose gel to the nitrocellulose/nylon membrane. In this upward capillary transfer procedure, a support is used which is placed in a reservoir of transfer buffer to elevate the entire assembly.

Which is the best material for Northern blotting?

A nylon membrane with a positive charge is the most effective for use in northern blotting since the negatively charged nucleic acids have a high affinity for them.

Where does the term Northern blot come from?

The term ‘northern blot’ actually refers specifically to the capillary transfer of RNA from the electrophoresis gel to the blotting membrane. However, the entire process is commonly referred to as northern blotting.
