Chapter I Introduction
The contents in this chapter include introduction of PCR technology, examples of PCR application,
introduction of Thermal Cycler and features of LifePro Thermal Cycler.
1. Introduction of PCR technology
Polymerase chain reaction (PCR) is a nucleic acid amplification that simulates natural DNA
replication in vitro. It takes 2 DNA chains to be amplified as template, uses a pair of artificially
synthesized oligonucleotide primer as mediator, and amplifies certain DNA fragment quickly and
specifically by thermostable DNA polymerase. Ever since PCR technology was invented by Mullis in
1985 and thermostable DNA polymerase was discovered by Erlich in 1988, this simple, fast, specific
and sensitive technology has been widely applied to life science areas with astonishing speed.
Remarkable achievements have been witnessed in cytology, virology, oncology, genetic disease,
forensic medicine, animal/plant immunology and etc. It is a milestone in contemporary molecular
biology development.
2. Example of PCR technology application scope
yResearch: gene clone, DNA sequencing, mutation analysis, gene recombination and fusion,
protein-regulating DNA sequence identification, transposition insertion site mapping, genetic
modification detection, synthetic gene construction, clone construction, carrier expression, certain
gene’s incision enzyme diversity detection and etc.
yClinical diagnosis: bacteria (spirochete, mycoplasma, Chlamydia, mycobacterium, rickettsia,
diphtheria bacillus, pathogenic E. Coli, dysentery bacillus, aeromonas hydrophilic and C. difficile
and etc.); virus (HTLV, HIV, HBV, HCV, HPVS, EV, CMV, EBV, HSV, measles virus, rotavirus,
parvovirus B19 and etc.); parasite (malaria and etc.); human genetic disease (Lesh-Nyhan
syndrome, Mediterranean anemia, hemophilia, BMD, DMD, cystic fibrosis and etc.)
yImmunology: HLA typing, T cell receptor or antibody diversity qualification, autoimmune disease
gene mapping, lymphokine quantification and etc.
yHuman genome project: DNA mark generated from scatter repetitive sequence, genetic map
construction (detect DNA, polymorphism, sperm drawing), physical map construction, sequencing,
expression map and etc.
yForensic medicine: crime scene specimen analysis, HLA-DQαanalysis and etc.
yOncology: pancreas cancer, rectal cancer, lung cancer, thyroid cancer, melanin cancer,
hematological malignant tumor and etc.
yHistology/population biology: genetic cluster research, evolution research, animal protection
research, ecology, environmental science, experimental genetics and etc.
yPaleontology: archeology and museum specimen analysis and etc.
yBotany/zoology: animal inflectional disease diagnosis, plant pathogen detection and etc.
3. Features of LifePro Thermal Cycler
LifePro Thermal Cycler is a PCR instrument with multiple functions and several applications. Below
are its features:
yUse advanced thermoelectric refrigeration technology from ITI of US and thermoelectric
refrigeration elements made under quality management of Japan, which are steady and reliable
in quality.
yTemperature can be changed as fast as 4°C /second. The speed to increase or decrease
temperature can be set as per need of experiment.
ySeveral modes for temperature control, better compatibility of reagent.
yLarge LCD screen, user-friendly operation interface, simple and easy operation
yPower-off protection available, programs can continue after power recovery.
yHeight and pressure of hot-lid can be set for different reaction tubes, which prevent reagent
evaporation and pollution effectively.
yConnect to ordinary computer by RJ45 standard interface, which is easy for software upgrading.
4. Use of LifePro Thermal Cycler
Integrating a number of advanced technologies, LifePro Thermal Cycler meets the demand of
