Dear All,

My product is an API that is available in concentration 20mg/ml.

We have to determine the endotoxin content of the same.

For this I prepared numerous dilutions starting from 1:10 and so on. I
found a positive gel clot formation till 1:3000 dilution.  Finally in
1:6000 dilution i found a negative result. I take 100 microliter of each
dilution and add 100 microliter of lyate. incubate as per
specified conditions and then check for clotting. My endotoxin
sensitivity is 0.125 EU/ml.

from above can anyone help to calculate the endotoxin content in the sample
in EU/mg. As per my calculation its between 75 to 125 EU/mg. Is it correct.

Please guide me. thanks in advance
