Abstract:
This invention provides the CD4-IgG2 chimeric heterotetramer, wherein the heavy chains of the chimeric heterotetramer is encoded by the expression vector designated CD4-IgG2HC-pRcCMV (ATCC No. 75193). This invention also provides the CD4-IgG2 chimeric heterotetramer, wherein the light chains of the chimeric heterotetramer is encoded by the expression vector designated CD4-kLC-pRcCMV (ATCC No. 75194). This invention also provides the CD4-IgG2 chimeric heterotetramer, wherein the heavy chains of the chimeric heterotetramer is encoded by the expression vector designated CD4-IgG2HC-pRcCMV (ATCC No. 75193) and the light chains of the chimeric heterotetramer is encoded by the expression vector designated CD4-kLC-pRcCMV (ATCC No. 75194). Finally, this invention provides a method of inhibiting HIV infection of a CD4+ cell, a method of preventing a subject from being infected with HIV, and a method of treating a subject infected with HIV so as to block the spread of HIV infection, using the above CD-4-IgG2 chimeric heterotetramers.
