Quantitative RT-PCR analysis of immune-related genes

Amounts of mRNAs of immune-related genes in hemocytes and fat body 3 h after injection of saline or 4 μg/ml active PP were analyzed by quantitative RT-PCR. Values indicate fold changes in mRNA quantities of PP-injected groups relative to saline-injected groups at 3 h after injection. Data represent mean ± S.D. of six experiments.

Tissue	Gene	Fold-change relative to saline injection
Hemocyte	tetraspanin E	1.8 ± 0.1
	actin A1	5.0 ± 1.4
	troponin I	6.9 ± 1.6
	ced-6	2.0 ± 0.2
Fat body	cecropin A	2.1 ± 0.5
	moricin	3.5 ± 0.9
	BmPGRP-S2	6.4 ± 3.9
