reproducibility is critical to producing quantitative protein maps. To establish the reproducibility of our imaging platform, 20 replicate voxels were dissected from a homogeneous region of liver tissue and analyzed using the nanoPOTS imaging platform. Figure2cshows coefficients of variation (CVs) for ...
The Walgreens pharmacy was sold out of at-home COVID tests. The shelves were empty and a sign at the pharmacy window said they were out of stock. Shoppers faced the same shortage at the CVS pharmacy nearby where the shelf was bare.
In 2022, Quest expanded its COVID-19 retail pharmacy testing footprint from CVS®, Walmart, Giant Eagle®, and Safeway to include a national collaboration with Rite-Aid®. Rite-Aid and Bartell Drugs® worked together to offer at-home PCR spec...
