用于样品制备的分子生物学大宗试剂和实验室耗材

Sample preparation for molecular biology research requires essential reagents and lab supplies that may include buffers, enzymes, primers, RNase-free tubes, tips and plates, centrifuges, thermocyclers, and protective lab equipment. Researchers and lab managers can stock up on reagents and lab supplies for sample preparation with Thermo Fisher. While performing experiments or running tests at larger scales and sample sizes, ordering bulk reagents helps reduce the cost of laboratory operations.

Bulk reagents for sample preparation

TRIzol RNA isolation

TRIzol Reagent is a patented formulation that supports the extraction of total RNA from tissues or cells, including lipid-rich and difficult sample types. The product has been used in countless labs and referenced in thousands of journal publications as labs use TRIzol Reagent to deliver intact, high-quality RNA from their chosen biological samples.

Phenol chloroform extraction

Phenol-chloroform is commonly used by molecular biologists to remove proteins from nucleic acids. The phenol is premixed with chloroform:isoamyl at a ratio of 25:24:1. 

Cells-to-CT

Cells-to-CT Bulk RT Reagents are large quantity reagents used for reverse transcription (RT) in the TaqMan Fast Advanced Cells-to-CT Kit and the SYBR Green Fast Advanced Cells-to-CT kit. 

RNAse controls

Prevent RNAse and DNase contamination using a combination of clean surfaces and nuclease free lab supplies. Improve the purity of your final sample by improving the control. Once you master the basics of RNAse control, you are ready to browse our selection of essentials.

DNA polymerases

DNA polymerases are enzymes that are essential for DNA replication, repair, and amplification. Bulk DNA polymerases are available at a lower cost, allowing researchers to purchase larger quantities and reduce the cost of laboratory operations while helping ensure consistency and reliability of results.

Nuclease-free water

Use nuclease-free water that’s used to prepare reagents or to resuspend precipitated RNA. We offer four primary formats of nuclease-free water: 

  • DEPC-treated
  • Non DEPC-treated
  • RT-PCR grade water
  • DNase-/RNase-free water

Lab supplies for sample preparation

Tubes and pipette tips

RNase-free tubes are indispensable for RNA-based applications. These tubes are treated to inactivate RNase, an enzyme that degrades RNA, thus helping ensure the integrity of RNA samples. They are commonly used in procedures such as reverse transcription, PCR, and RNA storage.

  • PCR tubes
  • Microcentrifuge tubes
  • Conical tubes

Multi-well plates

Multi-well plates from 6 well plates to 96 deep-well plates are used in so many life science workflows. Buying in bulk will reduce your cost and save you time on restocking your essential plastics. 

Centrifuge spin columns

Centrifuge spin columns are used for purifying, concentrating, and desalting biological samples. They have the power to separate DNA, RNA, and proteins from other cellular components by using centrifugal force to drive the sample through a filter or gel matrix, separating it based on size or other properties. Bulk centrifuge spin columns in larger quantities reduce the cost of laboratory operations and help ensure consistency and reliability of results.

Latex, nitrile and vinyl gloves

Gloves are an essential component of laboratory safety, protecting researchers from harmful chemicals, biological agents, and other hazardous materials. Bulk gloves are available in various materials, such as latex, nitrile, and vinyl, and can be purchased in large quantities at a lower cost. Choosing the right gloves is crucial, as they should be resistant to the chemicals and substances being handled and should fit properly to avoid contamination.
  • Latex gloves
  • Nitrile gloves
  • Vinyl gloves
