Average number of proteins per cell in the low and high expression levels for the three types of HIV receptors

Number of proteins	Low	High
CD4	$\mathrm{2,800}\pm 300$	$\mathrm{100,000}\pm \mathrm{13,000}$
CCR5	$\mathrm{3,600}\pm 800$	$\mathrm{125,000}\pm \mathrm{8,000}$
CXCR4	$\mathrm{15,000}\pm \mathrm{2,000}$	$\mathrm{120,000}\pm \mathrm{7,000}$

Low expression of CD4 and CCR5 conditions correspond to cells that were not induced by minocycline and/or ponasterone. High CD4 and CCR5 expression conditions correspond to those induced with 5 ng/mL minocycline and/or 1 $\mu$M ponasterone, respectively.
