Visual inspection of the full-length human TPO sequence against each consensus sequence revealed no similarity. Additional comparisons with the sequences of mouse, rat, canine, or human TPO were performed with the MacDNASIS Pro (Hitachi) homology match program (based on the Lipman-Pearson algorithm). No similarity was detected with a cutoff score >20 (Ktup value, the minimum number of consecutive residues that must match in a homology region in order for a score to be assigned, was set to 2).

6 TST into the polysome display system. Nucleotide abbreviations: Y = C or T; S = G or C; N = A, C, G, or T; K = G or T. Lowercase letters represent a mixture of 70% of the indicated base and 10% of each of the other three nucleotides. The degenerate codon YST encodes Cys, Ser, Pro, and Arg.

Rounds 1 and 2 were performed with standard procedures (13, 15). In rounds 3 and 4, 100 μM AF12191 was added to wells containing the receptor-bound plasmid complexes and incubated at 4°C for 45 min to accelerate the dissociation of lower-affinity peptides.

Automated "split and pool" oligonucleotide synthesis (26) generated a collection of oligonucleotides that encode the peptide sequence LAIEGPTLRQWLHGNGRDT in which the underlined amino acids were held constant and the remaining positions were either deleted, substituted with alanine, or conserved.

7 Ba/F3 cells. Selection was done in cell media (RPMI 1640, 10% fetal calf serum, 2 mM I-glutamine, 1× antibiotics-antimycotics) supplemented with WEHI-3 conditioned medium (10%) and G418 (1 mg/ml). G418-resistant cells were clone-sorted, and TPO-responsive clones were selected in media (RPMI 1640, 15% fetal calf serum, 2 mM I-glutamine, 1× antibiotics-antimycotics) supplemented with 1% supernatant from COS-7 cells transiently expressing full-length rhTPO.

Peptides were prepared by automated solid-phase synthesis and purified by C18 reversed-phase high-performance liquid chromatography (HPLC). Intramolecular oxidation of the thiols in cysteine-containing peptides was achieved by overnight incubation in 20% dimethyl sulfoxide (DMSO)-water, followed by purification of the cyclized peptide by reversed-phase HPLC. The structures of the purified peptides were confirmed by electrospray mass spectrometry.
