Immunogen | This antibody was raised by immunising alpacas with 1.0 mg polyclonal mouse IgG. Subsequently, the generation of nanobody immune libraries and the selection of antigen-specific nanobodies by phage display from these libraries were performed. |
Application Notes | TP886 nanobody can be used as an efficient high-affinity reagent for immunofluorescence. It was utilised in conjugation with two to three fluorophores in detection of mouse monoclonal IgG1 for the indirect immunostaining of HeLa cells where it performed exceptionally well as for a non-polyclonal antibody reaching similar signal strength to polyclonal agents when it was combined with another anti-IgG1 nanobody (Pleiner et al., 2018). Monovalent nanobodies can be also effectively used in a single step immunostaining procedure because they do not create large, cross-linked complexes with primary antibodies.TP886 was used as a secondary reagent; it was first incubated with a primary antibody and then a one-step immunostaining was performed (without the usual separate incubation with a primary and secondary antibody (Pleiner et al., 2018). |
