Sabaeus African green monkey CD4 molecules^a

CD4 clone	% amino acid identity to CD4 from:
	Human	Rhesus macaque	Sooty mangabey	Grivet AGM (Chlorocebus aethiops)	Vervet AGM (Chlorocebus pygerythrus)
AGM Sab 30	90.6	95.4	95.0	99.1	98.9
AGM Sab 31	90.8	95.6	95.2	99.3	99.1

^aCD4 was cloned from PBMC cDNA of two individual animals, yielding two AGM CD4 clones that are 98.9% identical at the amino acid level (5 amino acids are different).
