Basal levels of HSP70 protein in schistosome-resistant and schistosome-susceptible snail haemocytes are similar. a An equal number of haemocytes (approximately 1 × 10⁵ cells) from each snail strain were lysed and the proteins processed for western blotting with anti-HSP70 antibodies (upper panel). Blots were subsequently stripped of antibodies with a stripping buffer and re-probed with anti-actin antibodies (lower panel), to confirm equal loading of protein between samples. b Quantitative band analysis was used to calculate mean (±SEM) HSP70 protein levels in each snail strain relative to actin levels; n = 4 for each snail strain, performed in two independent experiments
