Uses of Blotting paper

• Absorbing Excess Liquids:

Blotting paper is used to soak up excess liquids from surfaces, samples, or equipment, helping to maintain a clean work area.

• Transferring Samples:

It can be used to transfer samples, especially in chromatography, where it helps in handling and separating substances.

• Wicking Action:

In various applications like paper chromatography, blotting paper helps facilitate the movement of solvent and analytes by capillary action.

• Sample Preparation:

Blotting paper can assist in preparing samples for further analysis, such as drying or concentrating biological specimens.

• Protecting Surfaces:

It is often used to cover sensitive surfaces in the lab, protecting them from spills or contamination.

• DNA/RNA Blotting:

In molecular biology, it is used in techniques like Southern and Northern blotting to transfer nucleic acids from gels to membranes for detection and analysis.

• Histology:

Blotting paper can be used to absorb excess stains or reagents in histological preparations, ensuring clearer slides for examination.

• Electrophoresis:

After gel electrophoresis, blotting paper can be used to wick away moisture from gels before transferring to membranes.

• Calibration:

It can serve as a tool for calibrating certain equipment or for standardizing measurements in various experiments.
