    A physical chemistry technique based on singlet oxygen luminescence at about 1270 nm and a biological cell membrane technique were used to study the quenching of singlet oxygen by four carotenoids bound to the surface of lymphoid cells. All the carotenoids studied showed a beneficial effect in cell protection, but there were subtle differences between them.
