Abstract

The present invention relates to improved primer process for detecting cell division cycle protein gene 6 in tumor. In the process of DNA extraction, RNA extraction, protein extraction, immunohistochemistry, reverse transcription (RT), PCR, Northern hybridizing, in-situ hybridizing and capillary electrophoresis, is adopted an improved primer, which has the hairpin structure formed with the downstream primer 5' end base sequence and the primer 3' end base in the first reaction. At normal temperature, the primer 3' end is in closed state, and after the primer is heated through reaction to the annealing temperature, the hairpin structure is opened for the primer to begin extending. The present invention has raised detection sensitivity and specificity, high reliability of clinical judgment of tumor cell course and prognosis, and important significance in preventing infection.

Description

technical field [0001] The invention relates to a method for detecting cell division cycle protein gene 6 in tumors by using improved primers Background technique [0002] With the development of molecular biology techniques, gene diagnosis and gene therapy are more and more widely used in clinic, such as the development and application of polymerase chain reaction (polymerase chain reaction, PCR). However, due to the characteristics of PCR technology itself, false positives and false negatives are prone to occur in clinical applications. In order to avoid these errors, many specific changes, designs, analyzes and experimental verifications should be made according to the characteristics of different nucleic acid fragments in the actual application of PCR. . This patent has made improvements in primer design to detect tumor cell division cycle protein gene 6. In order to improve its specificity and prevent pollution, specific design and experimental verification have been ...
