The assay known as PUBCHEM_BIOASSAY involves a High-Throughput Screening (HTS) Dose Response Counterscreen for assays that make use of the enzyme, b-galactosidase. It falls under the class of confirmatory assays, verifying the accuracy of an experimental result. Additionally, there are various related pubchem assays, including AID1777, AID1778, AID1785, AID1786, AID2284, AID2285, AID2348, AID2352, AID2357, AID2359, AID2370, AID2420, AID2478, AID2491, AID2492, AID2493, AID2495, AID2497, AID2498, AID2500, AID434981, AID449737, AID463105, AID485352, AID488822, AID488842, and AID488935. This assay targets a single protein directly and is categorized as confirmatory. The assay organism involved is Escherichia coli, and it is functional in nature. Based on the conditions and criteria of this particular assay, would the molecule in question be considered efficient and successful for fulfilling its intended purpose?
