    摘要: The present invention provides polypeptides having a length of up to 180 amino acids and containing a sequence selected from sequences identical or differing at most in 5 amino acids from the sequence: KSELAVEILEKGQVRFWMQAX21X22X23X24GNAKVNYIFNEKEIFEGPKYKMHIDXsoXsiXszGIIEM FMEKLQDEDEGTYTFQLQX76X77X78X79X80NHSTVVLVGDVFKKLQKEAEFQRQEWIRKQG (SEQ ID NO. 2), wherein X21X22X23X24 is selected from KAQQ (SEQ ID NO. 33), LSVF (SEQ ID NO. 34), ATPS (SEQ ID NO. 35), EIMW (SEQ ID NO. 36), DGSS (SEQ ID NO. 37), LLPL (SEQ ID NO. 38), WMWW (SEQ ID NO. 39), MNLY (SEQ ID NO. 40), MWRN (SEQ ID NO. 41), IMME (SEQ ID NO. 42), KHQL (SEQ ID NO. 43), HWQF (SEQ ID NO. 44), YAGN (SEQ ID NO. 45) and HGQW (SEQ ID NO. 46); X50X51X52 is selected from RNT, IMF, GHE, PSW, RAN, YFW, ITL, QAM, DMR, WLW, QGE, VQY and VSL; X76X77X78X79X80 is selected from SHHLG (SEQ ID NO. 47), FMLMM (SEQ ID NO. 48), VILIL (SEQ ID NO. 49), IVTPL (SEQ ID NO. 50), DFIIW (SEQ ID NO. 51), MWSE (deletion) (SEQ ID NO. 52), LYYAW (SEQ ID NO. 53), MMIEY (SEQ ID NO. 54), WMTQT (SEQ ID NO. 55), PQLWL (SEQ ID NO. 56), EPIFL (SEQ ID NO. 57) and QTATY (SEQ ID NO. 58); and optionally further having an affinity tag attached to the N-terminus or to the C-terminus of the sequence. These polypeptides mimic HIV-1 Env glycoprotein epitopes and are useful in preparation of antibodies and vaccines.
