HSP70 levels in clams during adaptation to various salinities∗.

Salinity (ppt)	HSP70 (relative density ×103)
	After 24 h	After 24 h	After 24 h
0.1	17.91	17.41	14.59
3	17.72	23.92	38.08
6	27.34	39.25	35.82

14	19.56	36.10	32.6
27	37.53	31.08	35.56

*Clams collected from Martinez marina (salinity: 10 ppt). Values represent relative density arbitrary units of bands detected by western blotting of pooled samples of five clams Potamocorbula amurensis, with no significant differences in temperature but salinity increasing in gradient manner in the sampling sites (Werner and Hinton, 2000 [106]).
