Someone would have some reference of Clostridium spp primer for qPCR to indicate? I'm looking for one that has less than 500 bp. I already used the sequence: F 5′-AAAGGAAGATTAATACCGCATAA-3 ′ and R 5′-TGGACCGTGTCTCAGTTCC-3 ′ and melt didn’t work with various annealing temperatures. I found only another 722bp. Maybe they don't search much for Clostridium spp, I already searched all possible databases.
