Unequivocal identification of the equine Dcfmqr phenogroup.

This study has yielded a new reagent that detects specific equine blood factors within the D phenogroup, such as Df, thereby enabling accurate genotyping of cells without the need for family data.

Objective of the Research

• The research aimed to produce an alloimmune reagent that can distinguish different factors within the D phenogroup of the equine blood types.
• The targeted factors for distinction within this phenogroup were Df, which were to be separated from those occurring in cefmqr and dfklr.
• Another main objective was to use this reagent in accurately genotyping Dc, d, f, k, l, m, q and r positive cells, without the need to rely on family data mainly used for similar analyses in the past.

Methodology

• The method involved producing an alloimmune reagent capable of distinguishing the equine factor Df in the D phenogroup, cfmqr, from that occurring in cefmqr and dfklr.
• By using this new reagent, the researchers could accurately genotype positive cells for the factors Dc, d, f, k, l, m, q, and r.

Results and Conclusion

• The research successfully produced a reagent that can unequivocally identify the Df factor within the D phenogroup from among other factors within the group and those occurring in cefmqr and dfklr.
• Using this reagent has resulted in correct genotyping of cells positive for the factors Dc, d, f, k, l, m, q, and r without requiring family data. This has resulted in a genotyping process that is potentially easier and more efficient than previous methods which require family data.
