Abstract
Introducing detailed procedures for the application denaturing gradient gel electrophoresis(DGGE) in the study of fungal community.The main procedure for DGGE includes: Extracting DNA directly from samples,PCR in the region of 18SrDNA or IST sequence using a primer with GC clamp in 5′,analyzing the PCR products in denaturing gradient polyacrylamide gel with a chemical denaturing gradient which could separate the different DNA fragments and then extracting bands from the gel.
A significance statement is not available in the OpenAlex record.
A contribution statement is not available in the OpenAlex record.
Method details are not available in the OpenAlex metadata.
Findings are not separately available in the OpenAlex metadata.
Limitations are not available in the OpenAlex metadata.
Application details are not available in the OpenAlex metadata.
