TABLE 1.

λ_max and spectral shifts from the native or deionized blue bR upon treatment of the bR sample with the detergents

Sample	λmax/nm	Δλmax upon detergent treatment/nm
Native	570	–
CHAPS treated native (in buffer)	560	−10 from native
Trition treated native (in buffer)	553	−17 from native
CHAPS treated native (in DDW)	560	−10 from native
Trition treated native (in DDW)	553	−17 from native
DeI bbR	603	–
CHAPS treated deI bbR (in buffer)	560	−43 from deI bbR
Trition treated deI bbR (in buffer)	552	−51 from deI bbR
CHAPS treated deI bbR (in DDW)	567	−36 from deI bbR
Trition treated deI bbR (in DDW)	552	−51 from deI bbR

CHAPS removes 75% of the lipids, and Trition monomerizes the bR samples.
