Effect of red seaweed sulfated galactans on initial steps of complement activation in vitro. [PDF]
Carbohydr Polym, 2021 The research described here presents data on the effect of galactans of red algae, carrageenans (λ/μ/ν-, κ-, κ/β-, and ι/κ-types), and agar on complement system activation in normal human serum. The experiments were based on well surfaces coated with triggering agents for binding initiating complement components -C3 and C4.
