Figure 2From: Phorbol esters and CAMP differentially regulate the expression of CD4 and CD8 in human thymocytesNorthern blot to determine the specificity of the Phorbol ester effect on the expression of CD3, CD4, CD8, and C-Ha-ras by human thymocytes. Experimental conditions are number-coded as follows: 1 = control; 2 = PMA-treated; PDB-treated; 4 = α-Phorbol Ester-treated; and 5 = β-Phorbol Ester-treated.Back to article page
