Representative RT-PCR analysis of fatty acid binding protein 3 (FABP3) expression in milk somatic cells (MSC) in response to caloric and protein stress (CAP). Cytokeratin19 was used as a loading control (a). Differential expression of FABP3 in MSC but not in leukocytes (WBC). CD45 was used as a specific marker of WBC (b). c Densitometry ratios of FABP3/Cytokeratin19 mRNA. Results are presented as means ± SD. Asterisk indicates significant increase of the ratio in CAP treatment (p < 0.001). BP Base pairs as size markers to indicate the length of the amplified fragment
