title: HPLC analysis of supernatant soluble factors from tumor cell variants with defined metastatic status.
abstract: In the present study, we report a simple and sensitive procedure to study supernatant soluble factors of short time cultured cells by high performance gel permeation chromatography (HPGPC). This procedure enables a direct analysis with no preparatory procedures prior to application in the chromatographic column and eliminates tedious and often low reproducible techniques, required during conventional assay of culture medium. In addition, we show that HPGPC analysis is suitable for discriminating between two variants of a rhabdomyosarcoma with different metastatic potential, while two distinct cell lines (3LL carcinoma and B16F10 melanoma), which do not differ in their metastatic potential, do not present noticeable qualitative differences in their chromatographic secretion pattern.
