The production of nanobody primarily required to select a camelid animal for immunization for about 5–10 weeks. The effector B cells are extracted from the plasma peripheral lymph blood of the immunized camel to isolate the total RNA and cDNA synthesis for sequencing. Phage display technology is used to screen the specific binding ability of […]

Nanobody (Nb) is the smallest natural antigen-specific binding functional fragment of about 12~15 kb (Figure 2D). The molecular weight of Nb is smaller than the monoclonal antibody mAb (~150 kb), Fab fragment (~55 kb) or HcAb (~90 kb) Figure 1A–C. Former study showed that these nanobodies can be genetically engineered from the heavy-chain antibody derived from camelids […]
Blog | Diagnostic Technical Articles 2019 nCoV (SARS CoV2 coronavirus) Spike trimer (P2-mutant, S1/S2 cleavage site(furin cleavage sequence)-mutant, trimerization modified) The world is in midst of the COVID-19 pandemic caused by SARS-CoV-2 (2019nCoV) infection. The Spike protein (S-protein) of SARS-CoV-2 (2019nCoV) mediates receptor (ACE2) binding and cell entry and is the dominant target of the […]
Nanobodies are frequently compared to polyclonal, monoclonal antibodies, antibody fragments, and small molecules. The production of nanobodies is simple and cost effective compared to the polyclonal antibodies. Besides, Nbs are stable in a wide range of temperatures and pH levels. Nanobodies are also compatible with genetic engineering methods, which allow scaffolding and alteration of amino […]
Nanobodies have been used for both diagnostic and therapeutic application due to its high stability, refoldability, and manipulable characteristics. In addition, VHH has been effectively used as a research tool. In Vitro Diagnostic Tests Nbs have been recommended for both in vitro as well as in vivo diagnostic tests. Early diagnosis of both infection and […]
Since 1975, monoclonal antibodies have been successfully used for the diagnosis and therapeutics. In 1993, heavy-chain-only antibodies which bind to antigens was discovered in camelids. The variable domain of heavy chain antibody (VHH) was called as nanobodies and it was anticipated as the better therapeutic antibodies in future due to its high stability, refoldability, and manipulable characteristics. […]
