Excellent and professional services
Rating: 5.0

  • Application Area:qPCR Probe-based Allelic Discrimination Assay

"I've used the Oligo Tech services numerous times over several years to help me with designing tricky dual-probe assays that can discriminate alleles that differ by a single SNP. Some of this has been trial and error, and the design team has been superb at helping perfect these assays along the way. Top-notch service!"

Good products with poor post-sale service.
Rating: 3.0

  • Application Area:PCR, RT-PCR

"The products are reliable and perform as expected. However, the shipping and post-sale had lost its original quality. They have been failing to provide tracking for shipping and orders have been delivered to a different location (State!) more than once. Several contacts to customer services by phone and email had proved unfruitful."
