Isotherm3G is a mesophilic DNA polymerase, perfectly suited for Isothermal amplifications. Isotherm3G has been mutated to have improved reverse transcription activity. It synthesizes DNA from both DNA and RNA templates with a high strand displacement activity allowing simplified one-enzyme RT-LAMP reactions.

Isotherm3G exhibits 5’ to 3’ polymerase activity but lacks any exonuclease activity. The product components have been optimized and are perfectly suited for loop-mediated isothermal amplification (LAMP) with optimal reaction temperature at 65°C.

Isotherm3G DNA Polymerase utilizes an aptamer-based warm-start feature to prevent false amplification at low temperatures. For more information, please contact us. 

The product is available also in bulk quantities with custom fillings and can be produced customized for example in a lyo-ready formulation.

Safety Features

1. User-Friendly Design: The chamber lid and tabletop are covered with heat-insulating resin materials, providing both protection against burns and an aesthetically pleasing appearance. The upward-opening flip-top door saves space, while the rounded corners prevent injury. The specially designed steam discharge and collection system minimizes steam burn risks and enhances operational convenience.

2. Interlock Mechanism and Safety Protection: The safety interlock system is designed to be more sensitive and secure. The chamber lid cannot be opened if there is pressure or steam inside the chamber. The lid can only be opened when the pressure gauge reads “0” MPa. The sterilizer will not start heating if the chamber lid is not properly locked. These features enhance the overall safety of the machine.

3. Over-temperature and Heating Protection: The system continuously monitors the temperature inside the sterilization chamber. If the temperature becomes too high or heating is abnormal, power will be automatically cut off to prevent overheating.

4. Automatic Fault Detection System: The machine performs an automatic self-check when powered on. If a fault occurs during operation, an audible alarm will sound, and a fault code will be displayed.

5. Lid Closure Check System: The system automatically detects whether the chamber lid is securely locked. If the lid is not properly locked, the sterilizer will not start.

6. Leakage, Over-current, and Short-Circuit Protection: If there is leakage in the heating elements or other components, or if over-current or short-circuit conditions occur, the system will automatically cut off power to prevent user injury.

7. Water Shortage and Independent Dry-Burning Protection: Equipped with a low water level sensor and independent dry-burning protection device, the system can monitor the water level in the chamber in real-time to prevent dry burning and avoid false readings. If the low water level sensor fails, the overheat and dry-burning protection system will automatically activate, cut off power to the heating ring, and sound an alarm to ensure safety.

8. Dual Pressure Protection: The system includes both a mechanical safety valve and an electronic over-pressure protection system. If pressure becomes abnormal, the system will relieve pressure and cut off power while sounding an alarm.

9. Back end Safety Testing: The system can be periodically tested for safety and protective measures.

10. Over-pressure Testing: Regular testing ensures that the instrument’s over-pressure protection system can automatically cut off power or that the safety valve can open to relieve pressure.

11. Performance Testing: The instrument’s safety performance has been tested by national authorized inspection agencies, and a test report is available.

Technical Parameters

Note: The upper limits for cooling lock door temperature and exhaust temperature are related to the boiling point.

Other Optional Accessories

1. Dot Matrix Printer: Capable of printing temperature, time, F0 value, and pressure data. USB data export and curve plotting.

2. Stainless Steel Basket with Base.

3. Pressure Sensor

4. Stainless Steel Bucket

5. Item Thermometer

6. 3Q Validation Adapter

Features and functions:

1. Large-diameter sterilization chamber：The 40 cm large-diameter sterilization chamber provides an exceptionally spacious environment to meet a wide range of sterilization needs.

2. Sterilization temperature：105-138℃.

3. Exhaust control ：After sterilization is complete, the exhaust valve can automatically open to release the exhaust at a pre-set temperature.

4. Verification interface: Provides temperature and pressure inspection ports for easy calibration.

5. Saturated steam monitoring：The system automatically monitors the expulsion of cold air to ensure a pure steam sterilization environment, guaranteeing optimal sterilization effectiveness.

6. Pressure performance：The chamber is designed to withstand a pressure of up to 0.35 MPa, and each unit is tested with a water pressure of up to 0.44 MPa. Advanced pressure protection ensures the safety load of the equipment.

7. Intelligent control system:The microcomputer chip-based intelligent control system monitors the temperature and pressure inside the sterilization chamber in real-time. The chamber lid can only be opened under safe temperature and pressure conditions. The system also provides fully automatic control of the sterilization process and allows for convenient maintenance, inspection, calibration, recording, and future upgrades.

8. Six preset programs:Includes six fixed programs for liquid sterilization and holding, solid sterilization and drying, agar melting and holding, and waste sterilization.

9. Memory storage system:Users can set their own parameters, create multiple programs, and access them at any time. The system allows for operation permissions to be set at three levels—user, administrator, and engineer—to facilitate effective use and management of the sterilizer.

10. Door-opening temperature: Each program can be set with a specific cooling lock door-opening temperature based on the thermal inertia of the sterilized items. This prevents users from opening the door when the items (especially liquid sterilized items) are still in an unsafe condition, thus avoiding burns.

11. Drying function: Thorough drying that meets CE standards, with a cooling lock mechanism.

12. One-touch inquiry function: Allows checking of current time, total number of sterilization cycles, fault occurrence time, and codes.

13. Scheduled start function: Allows you to set a start time so that the sterilizer automatically starts at the scheduled time.

Introduction

Free-circulating nucleic acids, such as tumor-specific extracellular DNA fragments and mRNAs in the blood or fetal nucleic acids in maternal blood, are present in serum or plasma usually as short fragments, <1000bp (DNA). HiPure Circulating DNA Midi Kit enables efficient purification of these circulating nucleic acids from human plasma, serum, or urine.

This product is for research use only.

Specifications

Principle

This product is based on silica Column purification. The sample is lysed and digested with lysate and protease, DNA is released into the lysate. Transfer to an adsorption column. Nucleic acid is adsorbed on the membrane, while protein is not adsorbed and is removed with filtration. After washing proteins and other impurities, Nucleic acid was finally eluted with low-salt buffer.

Advantages

• High yield – most optimal process, free DNA (>50bp) can be obtained to the maximum extent
• High concentration – low elution volume, ensuring high nucleic acid concentration
• High purity – low alcohol binding method, completely removing inhibitor and protein pollution
• High recovery – DNA can be recovered at thelevel of PG by silica gel column purification

Storage and Stability

Proteinase K, Carrier RNA should be stored at 2-8°C upon arrival. However, short-term storage (up to 12 weeks) at room temperature (15-25°C) does not affect their performance. The remaining kit components can be stored dry at room temperature (15-25°C) and are stable for at least 18 months under these conditions. The entire kit can be stored at 2-8°C, but in this case buffers should be redissolved before use. Make sure that all buffers are at room temperature when used.
