Figure 1From: Coupling of receptor interference and a host-dependent post-binding entry deficiency in a gammaretroviral envelope proteinBinding of virions containing the envelope protein of the SL3-2 MLV to permissive (NIH 3T3) and non-permissive (TE671) cells. The cells were incubated with supernatants from cultures that either did or did not produce viral particles at 4°C and subsequently labeled with anti-envelope antibodies for visualization in a flow-cytometer. (data are representative of several experiments). Light grey: supernatant containing no virions, dark grey: virion containing supernatant.Back to article page
