Antibody fragments, in particular the scFvs, Fabs, and V HH/V H retain full antigen-binding capacity and superior properties for research, diagnostic, and therapeutic applications. We offer the guaranteed antibody fragment services that provide high-quality soluble antibody fragments at very competitive prices and timelines. Customers simply provide us with the protein sequence of the antibody fragment and we will take care of the whole process from gene synthesis to final purified antibody fragment.

Gene synthesis and sub-cloning are included in the package – no additional cost to you.
Guarantee the solubility, purity, and amount of antibody fragment – no cost to you if we can not meet these order specifications.
We never refold fragments from inclusion bodies.
Competitive price - starting from $2,813.
Fast turnaround time - as soon as 7 weeks.

Terms and Conditions：Only those eligible scFv/VHH/Fab sequences determined by our scientists during pre-project analysis will qualify for the guaranteed services.
To increase the expression level of your antibody fragment, codon optimization may be performed during fragment gene synthesis.
We never refold the expressed antibody fragments.
There may be a few (<3) amino acid residues left over in the desired construct, which are usually glycine and serine residues and will not affect protein functionality.
Format of QA/QC: SDS-PAGE to determine the purity, and BCA™ Protein Assay or A 280nm to measure the protein concentration.
