Running out of one specific part can quickly stop a lab from processing COVID-19 checks. Back in March, services ran so low on specific kits that extract SARS-CoV-2 genetic info, scientists turned to social media to plead for other labs to send their additional kits their means.
The above absorbance measurements were not compromised by any absorbance by the indicator dyes because no leaching of the dyes into the eluates was noticed. Designed for single use to eliminate mud or different particles from the lens which will affect the picture quality.
