Antibody Purification and Labeling

Topics/Campaign Information

  • 2019/05/07
    We launched Antibody sequencing service.

Antibody sequencing

We provide sequencing service of valiable region of mouse monoclonal antibody. The antibody sequence information is essential for antibody engineering including humanization and drug development.
We analyze the sequence not only for hybridoma we have established as service, but also for hybridomas you already have.

  Service contents Deriverables Standard time period Price
Antibody sequencing ・Preparation of total RNA from mouse hybridoma.
・Synthesis of cDNA
・PCR amplification of variable region with primer mix specific for heavy chain and light chain each Sequencing of PCR amplified fragments
・Isolation of leader sequence by 5’ RACE PCR
・Identification of sequences from leader sequence to variable region

※Sample condition to be provided
Hybridoma (mouse) cell pellet (1 x 106 cells or more)
Antibody isotype should be IgG, and light chain should be κ chain.
Sequence data from leader to variable region in heavy chain and light chain
2 months JPY 500,000/
Options Culture of hybridoma
