Background:
- Swine leukocyte antigen (SLA) typing traditionally relied on serological, cytological, and biochemical methods.
- Advancements in molecular biology have introduced specialized techniques for SLA typing.
Purpose of the Study:
- To discuss the advantages and disadvantages of various SLA typing methods.
- To analyze SLA characteristics, including polymorphism and conserved functional aspects.
- To project future directions in SLA typing and correct existing literature errors.
Main Methods:
- Review of traditional typing methods (serological, cytological, biochemical).
- Evaluation of molecular typing techniques: PCR-RFLP, PCR-SSCP, Mass Spectrometry (MS), and DNA sequencing.
- Analysis of SLA polymorphic and conservative features (supertypes, supermotifs).
Main Results:
- Molecular methods offer enhanced precision over traditional techniques for SLA typing.
- DNA sequencing is essential for accurate determination of SLA-DQB gene polymorphism.
- Identified editorial errors in existing literature regarding SLA serological haplotypes.
Conclusions:
