What are eBlocks?

eBlocks Gene Fragments are double-stranded DNA fragments of 300-1500 bp in length. They are uniquely suited for high-throughput screening of multiple constructs, especially for antibody discovery scientists who want to obtain DNA constructs quickly and reliably for most cloning applications.

  • FAST time to ship (1–3 business days from order confirmation)
  • Budget friendly
  • Low screening effort to find your clone

New - eBlocks Gene Fragments up to 1'500 bp

Performance

Consistent high fidelity

All IDT gene fragments demonstrate a consistent, high sequence fidelity across various lengths, and eBlocks Gene Fragments are no exception (Figures 1 and 2).

Figure 1. The effect of error rate on predicted cloning success.
With a median error rate of less than 1:5000, eBlocks Gene Fragments demonstrate a high probability of first-time cloning success. This indicates that IDT Gene Fragments are more likely to give a correct clone the first time than fragments supplied by other vendors at comparable length ranges

Figure 2. Demonstrated cloning efficiency.
Compared to a leading provider, eBlocks Gene Fragments showed a significant improvement in cloning efficiency, leading to a reduction in the time and cost to find a correct clone.

Robust and flexible assembly

Thorough quality control testing of each eBlocks Gene Fragment ensures consistently high cloning rates for generating recombinant colonies. eBlocks Gene Fragments are compatible with many convenient cloning and assembly kits. Table 2 demonstrates the number of colonies needed to be picked to have a >90% chance of obtaining a desired clone.
