The Science of CRISPR Technology: Revolutionizing Genetic Research


I know what you're thinking: What do CRISPy Rice-cakes have to do with genetic research? Well, hold onto your hats (and your snacks), because we're about to delve into a different kind of CRISPR.

CRISPR — Clustered Regularly Interspaced Short Palindromic Repeats.

This cutting-edge technology is not about making your snacks crunchier; it's about revolutionizing genetic research and opening new doors in biotechnology.

Chemicals Used in CRISPR


  • Tris(2-carboxyethyl)phosphine (TCEP) - CAS Number: 51805-45-9


Usage: TCEP is a reducing agent that helps maintain the reduced state of sulfhydryl groups in proteins and nucleic acids. In CRISPR, it is used to reduce disulfide bonds in proteins, ensuring their proper folding and activity.

Significance: By preventing the formation of disulfide bonds, TCEP ensures that CRISPR enzymes, such as Cas9, maintain their functional structure, enabling them to accurately target and edit specific DNA sequences.


  • Ethylene glycol-bis(2-aminoethyl ether)-N,N,N',N'-tetraacetic acid (EGTA) - CAS Number: 67-42-5


Usage: EGTA is a chelating agent that binds to divalent cations, such as calcium (Ca2+), preventing them from interfering with enzymatic reactions. In CRISPR, EGTA is used to chelate calcium ions, which can inhibit the activity of nucleases and other enzymes.

Significance: By chelating calcium ions, EGTA ensures that CRISPR reactions proceed smoothly, without interference from calcium-dependent enzymes that could degrade the CRISPR components.


  • Polyethylene glycol (PEG) - CAS Number: 25322-68-3


Usage: PEG is a polymer that is used in CRISPR as a transfection reagent. It helps deliver CRISPR components, such as Cas9 and guide RNA, into cells by increasing their permeability.

Significance: PEG-mediated transfection enhances the efficiency of CRISPR editing by facilitating the uptake of CRISPR components into target cells, increasing the likelihood of successful gene editing.


  • Phenol:chloroform:isoamyl alcohol (25:24:1)


Usage: This mixture is used in CRISPR for phenol-chloroform extraction, a method used to isolate nucleic acids, such as DNA and RNA, from other cellular components.

Significance: Phenol:chloroform:isoamyl alcohol extraction separates nucleic acids from proteins, lipids, and other contaminants, purifying the DNA or RNA for downstream applications in CRISPR.



Usage: Chloroform is a solvent that is used in the phenol-chloroform extraction method to dissolve lipids and other hydrophobic molecules.

Significance: Chloroform aids in the separation of nucleic acids from lipids and proteins, ensuring the purity of the extracted DNA or RNA for use in CRISPR experiments.

Equipment Used in CRISPR


  • Lab Coating Equipment: Used for coating substrates with CRISPR components.
  • Lab Hydraulic Press: Used for pressing components together in CRISPR experiments.
  • Tube Furnace: Used for heating reactions in CRISPR experiments.


How CRISPR Works

CRISPR technology utilizes RNA molecules to guide the Cas9 enzyme to specific DNA sequences, where it induces double-strand breaks. This process allows for precise editing of the genetic code, enabling researchers to insert, remove, or modify specific genes with unprecedented accuracy.

Applications of CRISPR


  • Gene Editing: CRISPR has revolutionized gene editing, offering the potential to cure genetic diseases by correcting mutations at the DNA level.
  • Agricultural Biotechnology: In agriculture, CRISPR is used to develop genetically modified crops with improved traits, such as disease resistance and increased yield.
  • Biomedical Research: CRISPR is a valuable tool for studying gene function and disease mechanisms, leading to insights into various genetic disorders and potential treatments.
