Further guidance for diluent preparation is discussed in the following section. If the powder is seen to be floating on the liquid surface (Figure 1), a surfactant has to be used to wet the sample to ...

Diluted urine can make it difficult to get accurate results from a urine drug test. Here’s why it happens and what employers and other testers can do to decrease the chance of diluted samples.

The use of FCS as a sample diluent is vital for performance of the assay. Investigators first noticed the use of 10% FCS or ABS in PBS increased the OD reading of bound aCL Abs and markedly ...

Under the optimized PrepEngine condition, and utilizing the same diluent as that used in the manual sample preparation and extraction procedure, the PrepEngine was able to quantitatively extract the ...

Depending on the number of samples being analyzed, add 250 µL/well of Q Buffer or sample diluent (if samples are in another diluent, such as medium) to as many columns of the Max Plate (Gator Bio ...

Stock TEA samples were prepared by diluting 138 µL into 100 mL of diluent, where the diluent was different ratios of either DMSO:water or DMSO:0.01M sodium hydroxide (NaOH). Analysis samples were ...
