is there anyone working with hiv virus and can let me tell the procedure to check viral entry.
my experiment is i infect the macrophage cell with some lysates and then infect with HIV virus .
how does the lystaes helping or inhibiting the viral entry.
i have to use macrophage i cant use any reporter based assay.
i heard that we can check the viral entry by checking p24 but not sure of exact protocol.
it would be of much help if someone can help me come out of this.

because the first is done by microscopy... But not sure this is what you need, reading you post it seems not the case.
Check the paper for more information.

i just want to check or normalize by result with the entry of virus.
whether entry is same or not in both the cases.........control and test.
how can i do it in the macrophage cell line.

is there any other way except real time as it becomes difficult to routinely check real time in our institute.

ya i am transfecting and making virus in packaging cell line and use the supernatant to infect macrophages.
For which gene we should do the PCR is it necessary to to real time pcr or any general pcr can i do .
real time is not possible for me to do for every sample...........machine is too busy in my institute.
in case of FACS can i quantify it in terms of infection % in different test samples

As for FACS, you wouldn't need to sort the cells, just do flow cytometry to measure DNA amount.........the HIV protein VPR induces G2/M arrest, so you would need to wait until viral proteins are expressed before you check for a G2/M arrest. Nocadazole treatment of your cells should give you an idea what a G2/M arrest looks like by flow cytometry.
