Design of PCR primers for the detection of GKN1 mRNA in human sera. Structure of GKN1 gene and nucleotide sequence of GKN1 mRNA. The coding region is represented in capital letters, 5′ and 3′ UTR are in lower case, start and stop codons are underlined, intron regions are boxed. PCR primers pairs F1-R1, F2-R2, F3-R3 and F4-R4 are highlighted in yellow, green, azure and gray, respectively
