To provide an assay applicable to various species and short RNA types.

Main Methods:

Direct hybridization assay with no amplification steps.
Utilizes readily available technology and simple reagents.
Assay assembly and execution require minimal time and simple liquid addition.

Main Results:

The assay can be assembled in a few hours with straightforward design and execution.
Assay execution is rapid, taking less than 5 hours.
Enables profiling of hundreds of samples within days.

Conclusions:

The described assay offers a simple, rapid, and cost-effective approach to multiplexed miRNA profiling.
The assay is versatile, working for both animal and plant miRNAs, and is not species-specific.
This method facilitates large-scale miRNA profiling for diverse research applications.
