SRPX2 and melanoma: Cycle sequencing of the purified, melanoma-specific PCR fragment of 1274 bp and subsequent alignment of the obtained DNA sequence with the reference one exported from the Ensembl Genome Browser 91 revealed the presence of a 1096 bp long DNA segment that represents the intron 7/8 (1096 bp) of SRPX2 gene (ENST00000373004.4) (Figure 5C).
