Blot Plate: 96-Well Dot Blot Assay Plate

Vitrozm's Zoom Blot Plate is an innovative research lab tool for fast biomolecule analysis. Based on vertical and lateral flow principle, the proprietary Blot Plate allows users to perform high sensitivity dot blot assays in a familiar 96 well plate format without lengthy incubation and washing of a fragile piece of blotting membrane. Blot Plate is a stand-alone device without additional set up with vacuum, centrifuge, or shaker. A user only need to pipette samples and reagents into the wells and get the assay done. Blot Plate can be used with plate readers and imaging systems for fluorescent, luminescent and colorimetric signal analysis.

Harnessing the Power of Flow

It’s not a secrete that under flow condition, wash is far more stringent and affinity binding is far more efficient.  While lateral flow devices thrive as the most popular choice for point-of-care diagnostics, new generation vertical flow devices are becoming a simple and powerful lab essential for research scientists. 



Simply Works!

Fast Assay

>99% Saving

Superior Sensitivity

With Blot Plate, A typical dot blot assay can be performed comfortably in 1-2 hours.

Each assay well only takes 1-2 µl of antigen and antibody solutions for a dot blot assay, saving a significant amount of reagents comparing to conventional dot blot or ELISA assay.

Blot Plate uses high quality blotting membranes to deliver superior detection sensitivity with low background. 


Zero Cross-talk

Hassle Free

Robot Friendly

Each assay well is completely isolated, with no cross-contamination between samples,  wastes, or light signal. 

No shaking, no spinning, no aspirating, no dumping. Blot Plate is a stand alone device ready to use. There is no complicate assembly or use with centrifuge or vacuum source. All you need to do is pipette, detect, and dispose.

Blot Plate is compatible with liquid handling robots and high-throughput automation instruments.Assay kits can be developed upon the Blot Plate platform.



Black or White

Black-well Blot Plate is ideal for fluorescent and chemiluminescent detection using high sensitivity instruments. Opaque black wall blocks >99.99% of light from neighboring wells.

White-well Blot Plate is ideal for colorimetric assays on membrane or on beads - no matter you are using blue/purple chromogenic HRP or AP substrate, red gold nano particles, or colored latex beads, highly distinctive color will show against the white background, quantitative analysis can be performed using white-light epi-absorbance measurement.

New generation Blot Plate now includes plates with nitrocellulose membrane, the most frequently used  membrane for both protein and nucleic acid blotting assays. It is a proven medium for western, northern, and Southern blotting that produces excellent signal-to-noise results.

In addition, the new Blot Plate has

  • larger blotting area,
  • faster flow rate, and
  • larger volume capacity.

These improvements make it possible to work with samples like tissue culture supernatants, blood serum, cell extracts, or other preparations.

At Vitrozm innovation never stops.  We listen to customers' feedback and persistently improve the product performance with better design and better material.


What's in Your Plate?

With Blot Plate, we’ve radically simplified the most repetitive steps like rinsing and incubating so you can spend less time in waiting and react fast. With the right tools,  much more can be done with the same amount of precious proteins.
