Labeling DNA Probes03:31

Labeling DNA Probes

8.6K
DNA probes are fragments of DNA labeled with a reporter tag to enable their detection or purification. The resulting labeled DNA probes can then hybridize to target nucleic acid sequences through complementary base-pairing, and may be used to recover or identify these regions.
Radioisotopes, fluorophores, or small molecule binding partners like biotin or digoxigenin, are the most widely used reporter tags for labeling DNA probes. These labels can be attached to the probe DNA molecule via...

Southern Blot

Agarose gel electrophoresis is very useful in separating DNA fragments by size. Running a DNA ladder containing fragments of the known length alongside the sample helps determine the approximate length of the sample DNA fragments. However, additional steps are needed to verify the sequence identity of the sample DNA fragments.
Denatured DNA fragments must be transferred onto a carrier membrane from the gel to make it accessible to a probe - a small ssDNA fragment complementary to the target DNA...

Methods of Classification and Identification

318
Bacterial identification relies on a diverse array of techniques to classify and understand microorganisms, each tailored to uncover specific characteristics. Traditional morphological approaches, while still valuable, are limited for closely related or structurally simple organisms. Modern methods integrate biochemical, serological, genetic, and advanced molecular tools to achieve greater accuracy.Morphological and Biochemical TechniquesMorphological characteristics, such as cell shape and...

Area of Science:

  • Botany
  • Analytical Chemistry
  • Molecular Biology

Background:

  • Cosmetic ingredient suppliers and brands require reliable plant species identification.
  • Traditional methods for botanical authentication may lack sufficient accuracy and robustness.
  • The Lavandula genus is of significant interest in the cosmetics industry.

Purpose of the Study:

  • To evaluate the effectiveness of coupling chemical and genetic analyses for plant species identification.
  • To demonstrate the robustness of combined analytical methods in identifying species within the Lavandula genus.
  • To establish a reliable authentication tool for cosmetic plant ingredients.

Main Methods:

  • Utilized ultra-high-performance liquid chromatography (UHPLC) for chemical analysis.
  • Employed DNA barcoding with specific genetic markers for genetic analysis.
  • Analyzed eleven botanically authenticated lavender species.

Main Results:

  • Identified three key chemical compounds (coumaric acid hexoside, ferulic acid hexoside, rosmarinic acid) for differentiation.
  • Selected three genetic markers (RbcL, trnH-psbA, ITS) effective for species discrimination.
  • Demonstrated successful differentiation of eleven lavender species using the combined approach.

Conclusions:

  • The combination of UHPLC and DNA barcoding provides a robust system for botanical identification of lavender species.
  • This integrated approach offers enhanced reliability for authentication compared to traditional methods.
  • The study highlights the need for advanced tools combining genetic and chemical analysis in the cosmetics industry.
