title: Serum from LPS nonresponder C3H/HeJ mice does not support the formation of functional EAC reagents.
abstract: Serum from C3H/HeJ mice in contrast to serum from other mouse strains does not convert EA into EAC. A factor in supportive serum permits nonsupportive C3H/HeJ serum to produce a functional EAC-rosetting reagent. This factor is heat stable. Its concentration in serum parallels the sensitivity of mice to LPS. It is absent or inoperative when sensitivity is reduced on a genetic basis and increased when sensitivity is increased by treatment with BCG.
