Insights

We developed a new method to detect and quantify specific cytokine messenger RNA (mRNA) in pig blood cells. This fluorimeter-based assay offers a more efficient alternative to traditional polymerase chain reaction (PCR) methods.

Area of Science:

  • Veterinary Immunology
  • Molecular Biology
  • Biochemistry

Background:

  • Cytokines like interleukin 1alpha (IL1alpha) and interleukin 2 (IL2) play crucial roles in immune responses.
  • Accurate quantification of cytokine mRNA in peripheral blood leukocytes (PBLs) is essential for understanding immune status in pigs.

Purpose of the Study:

  • To develop and validate a novel fluorimeter-based, closed-tube polymerase chain reaction (PCR) assay.
  • To detect and quantify porcine IL1alpha and IL2 mRNA in PBLs.
  • To compare the performance of this new assay against a standard block-based thermocycler PCR.

Main Methods:

  • Development of a fluorimeter-based, closed-tube PCR assay.
  • Utilized melting curve analysis for quantification.
  • Targeted mRNA of porcine IL1alpha and IL2 cytokines.
  • Analyzed peripheral blood leukocytes (PBLs).
  • Compared results with a standard block-based thermocycler PCR.

Main Results:

  • The fluorimeter-based assay successfully detected and quantified porcine IL1alpha and IL2 mRNA.
  • Melting curve analysis provided reliable quantification data.
  • The closed-tube assay demonstrated comparable or improved efficiency over standard PCR.

Conclusions:

  • A novel, efficient fluorimeter-based PCR assay for quantifying porcine IL1alpha and IL2 mRNA in PBLs was established.
  • This method offers a valuable tool for immunological studies in swine.
  • The assay's closed-tube and melting curve analysis features enhance its utility and reliability.

Real Time RT-PCR

Real-time reverse transcription-polymerase chain reaction, or Real-time RT-PCR, is an analytical tool used to determine the expression level of target genes. The method involves converting mRNA to complementary DNA with the help of an enzyme known as reverse transcriptase, followed by the PCR amplification of the cDNA. These two processes can be performed simultaneously in a single tube or separately as a two-step reaction.
The real-time quantification of the number of amplified products is...
