Synstrands Gene/DNA Fragments

Synbio Technologies supplies our customers with double-stranded, sequence-verified Synstrands Gene Fragments in only a few business days. These fragments offer an affordable and accessible construction or modifications of genetic sequences. The various applications include antibody research and CRISPR-mediated gene/genome editing, being used as qPCR standards, etc. Synstrands Gene Fragments are available in two delivery forms: Eppendorf tubes or plates.

Competitive Advantages

  • Cost-effective approach: Fragment synthesis is cheaper and sometimes halves the price of synthetic genes synthesis; Competitive prices without sacrificing the overall quality.
  • No sequence restriction: Some sequences may be denied when running through the complexity test from our competitors. By applying different synthesis strategies, our comprehensive platform is capable of synthesizing any complex sequence.
  • Error-free option: DNA fragments are PCR products which contain certain error rate by its nature. We offer this basic option with very competitive price staring from $0.09/bp. Customers can request error-free fragments for their experiments with higher standards. 
  • Subcloning and sequencing: Construction of a plasmid can be tedious and stressful, especially with a tight timeline. We provide subcloning with vectors of your choice and sanger sequencing to ensure 100% sequence accuracy. Subcloning is free if your vector is under 6Kb.
  • Free codon optimizationImproves the synthesis feasibility of complex sequence; Enables a significant increase in protein expression.
