Where the antibody actually goes

To cover a membrane, the liquid only needs to form a few millimeters of depth over it. In a wide single-well tray, reaching that depth across the whole footprint can take 5–10 mL. Cut that same membrane into strips and incubate each strip in a narrow channel, and 1–2 mL per strip is enough for full, even coverage — a 3–5× reduction in prepared antibody per target.

Strip incubation has a second, bigger payoff: you can probe multiple targets from one gel. Cut the membrane by molecular weight, drop each strip into its own channel with a different primary antibody, and one gel yields data on six proteins — target, loading control, and four more — in a single incubation session.

One box, six antibodies, two full membranes

The catch has always been logistics: six strips used to mean six separate boxes jostling for shaker space. The Biofargo Western Blot Incubation & Washing Box packs the whole workflow into one 13.5 × 8.5 × 4.5 cm footprint:

• Upper layer: 6 independent strip channels (2.3 × 8.3 cm each). Six different primary antibodies side by side, no cross-flow between channels, 1–2 mL each.
• Lower layer: 2 full-membrane wells (6.4 × 8.4 cm each). When you need whole-membrane incubation — blocking, secondary antibody, total protein stain — you don't need a second piece of equipment.
• Chemical-resistant polypropylene (PP) with a smooth, low-binding interior, so precious antibody ends up on your membrane, not adsorbed to the box.
• Drainage outlets for clean, fast buffer changes between wash steps.
• Black or clear: black for light-sensitive fluorescent antibodies, clear when you want to watch your washes.

What the savings look like

Say you probe 6 targets a week. In single-well trays at ~6 mL each, that is ~36 mL of prepared antibody solution weekly. In strip channels at ~1.5 mL each, it is ~9 mL — a 75% reduction. For a lab diluting from a $300 vial, channel-based incubation routinely stretches one vial across three to four times as many blots. The box costs $19. It is not a purchase; it is a rounding error that pays for itself in the first week.
