[DIYbio] info on endotoxins

Hey guys,
What can you tell me about endotoxin removal from plasmid maxiprep?
Anyone know of the protocol for using Triton X-114 to remove
endotoxins? It's some sort of aqueous phase separation. I'm not too
sure.

Is there a cheap way to detect endotoxins, e.g., before and after
purification? The gel-clot LAL assay is probably around $200 for 20-30
assays but I just need to test 7 samples.

Thanks
