TOP1, Human (765a.a, sf9, His)

The TOP1 protein is critical in cellular processes, mitigating DNA supercoiling and torsional tension during replication and transcription. It does this by transiently cutting and rejoining a DNA strand, introducing breaks through transesterification. TOP1 Protein, Human (765a.a, sf9, His) is the recombinant human-derived TOP1 protein, expressed by Sf9 insect cells , with N-His labeled tag. The total length of TOP1 Protein, Human (765a.a, sf9, His) is 765 a.a., with molecular weight of ~93.1 kDa.
