How does the Human Transcriptome Probe Panel v2 differ from the Human Transcriptome Probe Panel v1?

Question: How does the Human Transcriptome Probe Panel v2 differ from the Human Transcriptome Probe Panel v1?

Answer: Below is the high-level differences between two Human Transcriptome Probe Panels used with Visium Spatial Gene Expression for FFPE and Visium CytAssist Spatial Gene Expression assays:

1. 1. There are now primarily three probe pairs designed against each gene instead of a single probe pair.  A small portion of the highest expressing genes contains a single probe pair (<10% of genes). 
   2. ~54,000 probe pairs are used to detect >18,000 genes. 
   3. Now includes Nuclear-encoded mitochondrial genes.
