Technical Summary

Stage 1: Total RNA extraction from the hybridoma cell pellet
Total RNA will be extracted and purified from the hybridoma cell pellet. The quality of the total RNA will be assayed on Agilent Bioanalyzer 2100.

Stage 2 : Reverse transcription
Total RNA will be transcribed into cDNA using either an Oligo(dT) or a gene-specific anti-sense primer. Specific murine and human constant domain primers could be used to determine the isotype of the antibody.

Stage 3 : PCR or 5’ RACE amplification of heavy and light chains
Degenerate VH and VL primers are used to amplify the variable domains from the cDNA.
For 5’RACE, our proprietary adaptor is added to the 3’ end of the cDNA. The heavy and light chains can now be amplified with our proprietary adaptor (sense primer) and a gene specific (CH/CL, reverse primer). PCR products will include the sequence of the signal peptide, variable domains and constant domains up to the reverse primer.

Stage 4 : Cloning into a standard sequencing vector
The PCR products will be gel purified to clone into a sequencing vector for sequencing.

Stage 5 : Sequencing analysis
As standard we will sequence a minimum of 12 independent clones for each chain.

Stage 6 : Final Report
A report is detailed the work performed which includes sequence alignments of the heavy and light chains and is e-mailed to the client.
