The well position is also standardized, but only for 96- , 384-, and 1536-well plates. These are generally well followed by manufacturers: Well Positions [16] [17] 96-well plates have a 9 mm well-to-well spacing, 384-wells a 4.5 mm spacing, and 1536-wells a 2.25 mm spacing. A notable characteristic is that the well array is symmetrical when the ...
Here, I redesigned the 96-well plate figure working from an overlay of a 96-well plate manufacturer technical drawing, and the official SLAS/ANSI 96-well plate size standards.

Plate readers, also known as microplate readers or microplate photometers, are instruments which are used to detect biological, chemical or physical events of samples in microtiter plates. They are widely used in research, drug discovery , [ 1 ] bioassay validation, quality control and manufacturing processes in the pharmaceutical and ...
BCA protein assay in a 96 well plate. The bicinchoninic acid assay (BCA assay), also known as the Smith assay, after its inventor, Paul K. Smith at the Pierce Chemical Company, [1] now part of Thermo Fisher Scientific, is a biochemical assay for determining the total concentration of protein in a solution (0.5 μg/mL to 1.5 mg/mL), similar to Lowry protein assay, Bradford protein assay or ...
The fluctuation method is performed entirely in liquid culture and is scored by counting the number of wells that turn yellow from purple in 96-well or 384-well microplates. In the 96-well plate method the frequency of mutation is counted as the number of wells out of 96 which have changed color.
In the nuclease hybridization assay, the oligonucleotide analyte is captured onto the solid support such as a 96-well plate via a fully complementary cutting probe. After enzymatic processing by S1 nuclease, the free cutting probe and the cutting probe hybridized to metabolites, i.e. shortmers of the analyte are degraded, allowing signal to be ...
1929: Blowout prevention equipment becomes mandatory on oil and gas wells drilled in California. 1929: First well logs in California run by Shell in a well near Bakersfield (Kern County). 1930: Deepest well in the world is Standard Mascot #1, rotary drilled to 9,629 feet at Midway-Sunset. 1931, 1939: voters reject referendum on oil conservation
The stationary phase comes in the form of a packed syringe-shaped cartridge, a 96 well plate, a 47- or 90-mm flat disk, or a microextraction by packed sorbent (MEPS) device, a SPE method that uses a packed sorbent material in a liquid handling syringe. [7] [8] These can be mounted on its specific type of extraction manifold. The manifold allows ...
