Antibody Sequencing: Top 3 Mistakes to Avoid

Our expertise helps you avoid common pitfalls when sequencing antibodies: 1) impurity of hybridoma cells, 2) mutations introduced by PCR, and 3) inaccurate or misaligned full sequences. Learn more from our success to overcome these problems »


  1. Impurity of hybridoma cells: (hybridomas may contain pseudogenes and mRNAs encoding non-functional antibodies, which may be amplified by primer pairs intended to clone the target antibody)
    • GenScript will sequence 5 independent clones for each chain, to ensure accuracy.
    • GenScript can also express the whole IgGs in a mammalian expression system and further confirm the antigen-antibody binding performance to double-ensure accuracy.
  2. Mutations introduced by PCR: During the amplification of the cDNA, the use of degenerate primer sets means there is the chance of mutagenesis.
    • GenScript always uses both 5'- and 3'- RACE (rapid amplification of cDNA ends) to ensure accuracy of amplified products.
    • GenScript always performs full length sequencing of the variable region, which ensures the accuracy of the sequence span, from leader sequence to the start of FR1 region.
  3. Inaccurate or misaligned full sequence (once the individual sequences are obtained for each chain, they must be aligned properly to ensure the full sequence is accurate)
    • GenScript has sequenced over 4,000 mAbs, our expertise ensures the sequence you receive is 100% accurate.
