The cancer cell lines used in the present study, B16-F0 [murine melanoma;
CRL-6322™, American Type Culture Collection (ATCC), Manassas, VA, USA], B16 melanoma 4A5 (murine melanoma; 94042254; Sigma-Aldrich Chemie GmbH, Munich, Germany), A375 (human melanoma;
CRL-1619™; ATCC), HepG2 (human liver carcinoma;
HB8065™; ATCC), MCF7 (human breast carcinoma;
HTB22™; ATCC) and
MDA-MB-231 (human breast carcinoma;
HTB26™; ATCC), were acquired from Sigma-Aldrich Chemie GmbH and ATCC as frozen items.
The specific reagents for cell culture [
Dulbecco's modified Eagle's medium (DMEM); Eagle's Minimum Essential Medium (EMEM)], fetal bovine serum (FBS), antibiotic mixture of penicillin/streptomycin,
phosphate-buffered saline (PBS), Trypsin/EDTA and
trypan blue were acquired from Sigma-Aldrich Chemie GmbH and ATCC.
Ethanol,
formic acid,
trifluoroacetic acid and
acetonitrile were acquired from Sigma-Aldrich Chemie GmbH. α-cyano-4-hydroxycinnamic acid (Bruker HCCA matrix) and protein I calibration standard were acquired from Bruker Daltonics (Bremen, Germany).
