Abstract
Description
technical field
[0001] The invention relates to a breast cancer early-warning chip for the simple and rapid detection of type I thymidine kinase gene protein (hTK1), which is developed by cross-scientific technologies such as genetic engineering methods and molecular immunology techniques, and is mainly used for early warning of the risk of occurrence or development of female breast cancer At the same time, it can also be used as a new health care method for women's health protection reminder and clinical diagnosis of early breast cancer. Background technique
[0002] Background on breast cancer and its diagnostic technology: Breast cancer is a common and frequently occurring malignant tumor in humans. It is a malignant tumor of epithelial origin and a systemic complex disease. The most common early clinical signs and manifestations mainly include painless lumps in the breast and armpits, changes in breast shape or size, inverted nipples, nipple discharge, "dimple-like" depr...
Examples
Embodiment approach
[0052] ① Cloning and sequence analysis of hTK1 gene:
[0053] 1) Reverse transcription PCR amplification of TK1cDNA: Extract RNA from 5 million Hela cells with Trizol reagent kit that can extract total ribonucleic acid (RNA) from animal cells and tissues, bacteria, fungi, etc., and treat with methotrexate for 48 hours , and after purification, a highly efficient alkylating agent-diethyl pyrocarbonate (DEPC) was used to dissolve the precipitate in water to obtain 30 μl. Since DEPC can destroy ribonuclease (RNase) activity, it can remove RNase contamination.
[0054] When performing reverse transcription, add 5-fold buffer: 4 μl, primer Oligo-dT (0.5 μg / 1 μl) 1 μl, deoxynucleoside triphosphate (dNTP) at 10 mMol / L concentration: 2 μl, RNA: 10 μl, deionized water : 2 μl, mixed thoroughly, and placed in a constant temperature water bath at 70°C for 10 minutes; then, placed on ice for 2 minutes; added 1 μl reverse transcriptase (50 U, Roche), mixed well, and placed in a water bath ...
