This protein is a preparation of human tenascin purified by precipitation, concentration and dialysis from tissue culture supernatant of the glioblastoma U-251 MG, formally distributed as U-373 MG, an astrocytoid adherent cell line, an over producer of human tenascin.
This product has been prepared from Human placenta and is free from other Collagens, Human serum proteins and non-collagen extracellular matrix proteins. It reacts with anti-Collagen Type I. Reaction of Human Collagen type I with anti-Collagen II, III, IV, V or VI is negligible (typically less than 1% cross reactivity was detected by ELISA).
Human Very Low Density Lipoprotein (VLDL). Single arc by IEP against antisera to whole human serum. Essentially free of other plasma lipoproteins as determined by electrophoresis using Fat Red 7B staining for lipids and Coomassie Blue for proteins.
Composition: 88-95% lipid; 5-12% protein.
