Abstract
Here, we provide a detailed protocol describing a SDS-PAGE based procedure to assay in gel neutral lipase activity. Total protein extracts are separated by SDS-PAGE and gels are treated with lipase substrate-α-naphthyl palmitate. This long-chain fatty acid ester is hydrolysed by lipases present in the gel. The product resulting from this reaction can be then visualized in the gel as yellow-brownish activity bands. This relatively simple and effective method of lipase assay detection can be used for crude protein extracts from different plant tissues.
