I am not a chemist but B12 does seem to be an inherently stable molecule, not least indicated by the fact that the boxes of it have long shelf from production dates on them
These approaches ensure a 1 nM effective concentration of the fluorescently labeled nanobody (NbLumSyt1-pH/Nb-At647N or NbLumSyt1-HALO/JF549) on the imaging plate, allowing partial labeling of the Syt1 nanobodies without over-saturating the fluorescent signal enabling single molecule detection
Combine them only at the research stage
The resultant solution can be transferred to small vials or ampules and can be further subjected to lyophilization
