During preservation, hybridoma cells may lost antibody genes, or difficult to be recovered, or even dead, which will affect antibody production. In order to preserve and stably produce excellent antibodies for long time, antibody genes in hybridoma cells can be extracted and sequenced. Nucleotide sequences are obtained and stored as DNA for recombinant expression and production at any time.
The hybridoma antibody gene sequencing service provided by Sino Biological not only can quickly obtain the mAb gene, but also can use its advanced codon optimization and gene synthesis strategies to engineer the expression and purification of the antibody.

1.Number of cells >1×10^6 or cells treated with Trizol by following steps:
a. The cells and supernatant are blown, number of cells >1×10^6, cells are live and in good condition.
b. Cells are centrifuged, and then discard the supernatant, 1-2 ml Trizol (1×10^6 add 1 mL, 5×10^6-10^7 add 2 mL, 1×10^8 add 3 mL) is added according to the amount of cells. Store at -80°C and prepare for RNA extraction.
2.Provide the information of antibody subtypes
3.Species and sources of hybridoma cells
