Reduced expression of Ca2+-regulating proteins in the upper gastrointestinal tract of patients with achalasia

Figure 3 Protein expression of SERCA 2b, CSQ, and CRT in biopsies of esophageal body (EB, A) and lower esophageal sphincter (LES, B) from patients with achalasia or healthy controls. Protein expression was quantified using [¹²⁵I]-labeled protein A for detection of primary antibodies. Radioactive bands were visualized and quantified using a PhosphorImager. Data are presented as mean ± SE of n patients. ^aP < 0.05 vs control.
