Molecular weight of an antibody

Immunoglobulin G (IgG) antibodies are large globular proteins with a molecular weight of about 150 kDa made of four peptide chains. It contains two ....

Dec 3, 2019 · The smaller molecular weight can expand the range of drug-dosing modalities to include inhalation, needle free, oral, topical, and ocular delivery [298,299,301,302]. In addition, the VHH CDR3 is often longer than the IgG VH CDR3, potentially allowing it to form more favorable contacts with its binding epitope . The predicted protein molecular weight (MW) is the sum of all protein amino acid MWs. It can be calculated using, for example, the online ExPASy tool. However, the calculated MW may be different from that observed on the Western blot. The figure below summarizes the most common reasons as to why this may occur (Figure 1).
