Recombinant Antibody Production
We provide various types of recombinant antibody production services. We produce full length antibodies and fragment antibodies, e.g. scFv, Fab, you only need to provide sequences. Our antibody can be applied to affinity determination, activity assay and interaction studies.
Mammalian Expression System
We provide prokaryotic expression services, including expression of soluble proteins and tag-free proteins, large-scale fermentation. We guarantee delivery of a soluble proteins. If the protein is not soluble, you will not be charged. The shortest time to delivery is only 5 weeks.
Recombinant Antibody Production
We provide protein transient transfection expression in mammalian cell. We are equipped with a 100-grade clean cell room. Through engineering regulatory elements in HEK293 and CHO cells, proteins with a variety of complex modifications can be expressed, allowing rapid production of highly active proteins in small quantities.
Biomolecular Interaction Analysis
We provide molecular interactions analysis services, including protein-small molecule, protein-protein, and antigen-antibody interactions. We can carry out in vivo or in vitro interaction analysis, which allows us to examine intermolecular interactions both qualitatively and quantitatively (by determining affinity constants, Kd, Ka, and KD).
Antibody Production
We provide stable cell line construction services, including insertion or knockout of the gene of interest, as well as screening out positive cell pools or single cell clones . The shortest time to delivery is only 3 months.
Bioinformation Tools
We provide antigen and antibody production services. Our antibody production services include monoclonal (ELISA>1:128000) production and polyclonal antibodies (ELISA>1:64000). The final deliverable is 2-5 mg antibody.
