Spectral response of BV2+ towards increasing levels of spiked Hcy in reduced human plasma upon irradiation. Absorption spectra of solutions of BV2+ (20 mM) in 25% human blood plasma and 0.5 M Tris buffer (pH 7.0) spiked with 0–5 µM Hcy. Plasma (25% v/v) was added to an argon-saturated solution of viologen, thiol and buffer, and irradiated for 15 min using a Reptisun™ lamp.
