Tested Data
IF
Figure 1 HEK293T cells were transiently transfected with various NP expression plasmids indicated at the top of the panels.
At 24 h post-transfection, the cells were probed with 10 nM of the various sdAb-APEX2 fusion proteins indicated to the left of the panels, developed with 3, 3'-diaminobenzidine (DAB) for 1 min and visualized with light microscopy at 10× magnification.

Figure 3 Visualization of MLAV NP by anti-MARV sdAb–APEX2 Fusions.
DAB developed Western blots of HEK293T cell lysates after the transient expression of the MARV, MLAV, EBOV NP genes, or a control β-galactosidase gene and probing with 10 nM of either monomeric (sdAb A and sdAb E2) or dimeric (sdAb A2 and sdAb E2) APEX2 fusion proteins. Coomassie-stained 12% gel of the lysates to show equivalent loading. Molecular weights of markers are indicated to the left in kDa.

Figure 6 Locating the region of nucleoprotein (NP) bound by sdAb and establishing EC50 values.
Purified recombinant MARV or Bundibugyo (BEBOV) NP polymers were titrated over passively immobilized anti-MARV NP–sdAb, and captured NP subsequently detected with a constant amount of each phage displayed sdAb followed by anti-M13–horseradish peroxidase (HRP) conjugate.

Figure 7 Locating the region of nucleoprotein (NP) bound by sdAb and establishing EC50 values.
Fusions of sdAb–gluc were titrated over passively immobilized MARV NP polymer to determine EC50 values. Each titration was performed in duplicate wells with a negative control binding curve on BEBOV NP subtracted from each MARV curve.

SDS-PAGE
Figure 1 Recombinant Llama Anti-MARV NP Single Domain Antibody (A) (PABC-560) in SDS-PAGE
SDS-PAGE analysis of PABC-560 in reduced (Lane 1) and non-reduced (Lane 2) conditions. Gel stained for 30 minutes with Coomassie Blue. As a result, different β-mercaptoethanol-reduced proteins (Heavy chain and Light chain) migrate as about 50 kDa and 25 kDa, respectively.
The purity of PABC-560 was greater than 95% as determined by SDS-PAGE.
