Primer sequences used for the test describe in ISO18074 Textiles -- Identification of some animal fibres by DNA analysis method – Cashmere, Wool, Yak and their blends

The sequences of primer sets for the testing described in ISO18074 were written below. These were mentioned in the section 4.9 – 4.12, and 7.21 in the International standard. Annealing temperature of PCR (9.5.2) should be set for 62 ˚C for those primer sets.

4.10 primer for cashmere (DNA fragment of 239 bp should be amplified)
