Purpose of the Study:
- To present a standardized protocol for lectin blotting.
- To improve the detection of glycoproteins from cell membrane fractions.
- To address the limitations of high background and lab-to-lab variation in lectin blotting.
Main Methods:
- Protein extraction and quantification from cell lysates.
- SDS-PAGE for protein separation.
- Lectin peroxidase labeling and lectin blotting procedures.
Main Results:

Western blotting is an analytical technique for protein identification. It has various applications in immunology and medicine, including detecting diseases like bovine spongiform encephalopathy, mad cow disease, and human and feline immunodeficiency virus from biological samples.
The technique begins with separating proteins from the sample using sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE), followed by protein transfer, immunoblotting, and finally, protein detection.

Agarose gel electrophoresis is very useful in separating DNA fragments by size. Running a DNA ladder containing fragments of the known length alongside the sample helps determine the approximate length of the sample DNA fragments. However, additional steps are needed to verify the sequence identity of the sample DNA fragments.
Denatured DNA fragments must be transferred onto a carrier membrane from the gel to make it accessible to a probe - a small ssDNA fragment complementary to the target DNA...
