Antigen: rat soluble guanylate cyclase β1 subunit amino acids 188-207 (EDFYEDLDRFEENGTQDSR; last D=E in human and bovine) · Host: rabbit · Application(s): WB and IHC · Soluble guanylate cyclase is a heterodimeric enzyme, composed of a and b subunits, that catalyzes the synthesis of cGMP from GTP. The enzyme is activated by the binding of nitric oxide to the heme group of the enzyme.¹ The cloned b1 subunit of guanylate cyclase from human, bovine, and rat sources contains 619 amino acids and has a molecular mass of approximately 70,000.^2,3,4 The a1 subunit contains 690-717 amino acids and has a molecular mass of 77-82 kDa.^3,5,6 This antibody will specifically recognize only the b1 subunit of soluble guanylate cyclase.
