Table 1. The initial rates of peptide/DR1 complex formation for tested peptides with and without accessory molecules.

Observed Initial Binding Rates in interaction of DR1 with Fluorescent Peptides#
Peptides	DR1 alone	+ DM	+ DO	+ DM and DO
HA(306-318)	132	463	523	1779
HA(Y308A)*	118	331	184	234
HA(anchorless)	803	2141	385	651
H5N1-HA1(259-274)	98	665	257¶	2197
CII(281-295)	500	1593	137	1002

^#Initial Rates were determined for 1 hour (Response; Arbitrary Fluorescence Units min⁻¹).

^*The effect of DO on HA(Y308A) was determined by using co-expressed DM/DO complex.

^¶Determined in a separate experiment.
