Hi! Jun! Konnichiwa! Sorry for using Japanese here :-)
I don't know how to post response, so asked my friend Dr. Yoshida
to forward following LCR message which was found from my log stock
If you have any questions, please don't hesitate to connect NIFTY-
serve, and join us "Bio-Net baiofooramu (Janglish style of BIOFORUM).
We CAN accept messages written in Japanese Kanji and Kana.

;According to the original paper (see below), LCR can definitely detect 200
;target sequences in a sample. Whether it can go lower wasn't tested.
;LCR won't lower your primer bill, as you still have to make oligos.
;However, you don't need any nucleotides.
