Lyophilisation leaves a cake whose volume depends on what was in the solution before drying. With a milligram of protein and little excipient, the result may be a thin film or a few flakes rather than an obvious plug.
An apparently empty vial at this mass is usually the normal appearance of the product, not a missing fill. It is worth knowing before opening a first carton.
Proteins stick to glass and plastic. At milligram scale the proportion lost to a vial wall, a pipette tip or a tube is small in absolute terms and can be significant relative to the amount present — which is why carrier protein appears in so many methods sections for low-concentration work.
Whether a carrier is appropriate depends on the assay; it is a design decision with consequences for what else is in the system, not a default.
Add the diluent down the vial wall rather than directly onto the cake, and let it dissolve rather than forcing it. Proteins are sensitive to shear and to foaming, and vigorous agitation is a reliable way to lose activity without changing anything visible.
The pack includes a 3 mL bacteriostatic water vial. REVIVE LAB UAE provides no guidance on volumes, concentrations or use.
Note the appearance on opening, the diluent volume and the date. A solution whose preparation is undocumented cannot be compared with the next one, and at this scale small handling differences are the likeliest explanation for a result that will not reproduce.
