Normalized cDNA Library Construction Service

Normalized cDNA libraries are produced using a special normalization procedure which can enhance the gene discovery rate of a cDNA library and facilitate the identification and analysis of rare transcripts. This procedure is imperative for transcriptome sequencing, and useful in other applications, such as functional screening, construction of specific RNA libraries, and transcript end sequence profiling. As a leading supplier in cDNA library construction services, Creative Biogene can provide you with high-quality normalized cDNA library construction services to ensure your satisfaction in a timely and professional manner.


  1. Discovery rare genes.
  2. Transcriptome sequencing


  1. High normalization degree.
  2. Low vector background and high percentage of recombinants.
  3. The libraries can be made directionally and in the vector of your choice.
  4. Competitive prices.
  5. Fast turnaround time.

Creative Biogene offers subtractive cDNA library construction services for your scientific research as follows:

  1. Extraction RNA from a variety of samples.
  2. Synthesis full-length cDNA and normalization.
  3. Directional cloning the target cDNAs into any vector.
  4. Production of a library with at least 106 cfu.
  5. Verification of library quality by randomly picking clones and determining insert sizes by restriction digest or DNA sequencing.
