It’s part of our commitment to more sustainable packaging solutions, with ambient deliveries using eco-friendly materials such as recyclable cardboard instead of polystyrene.
What you need to know
- Ambient shipments come clearly marked on the delivery note.
- No ice will be included in ambient shipments, but mixed orders (ambient and cold-chain items) will still arrive with ice packs to protect temperature-sensitive products.
- Warranty coverage remains fully valid, aligned with our validated shipping method.
- Please store the product as per the datasheet instructions upon receipt.

Biological function summary
Topoisomerase I plays a significant role in the modulation of DNA topology ensuring proper chromosomal functions during cellular proliferation. It serves as a single polypeptide and does not require a companion for its activity unlike other topoisomerases that may function in complexes. The enzyme's ability to relieve torsional stress in DNA is essential for maintaining genomic stability and facilitating the smooth progression of the replication fork.
Pathways
Topoisomerase I is vital for DNA replication and transcription processes. It works in concert with other proteins such as helicases and ligases to ensure efficient unwinding and rewinding of DNA strands. The enzyme participates in the DNA damage response pathway where it interacts with proteins like PARP1 to coordinate repair processes. Its action is important in both the S phase of the cell cycle where DNA synthesis occurs and in the G0 phase where cells are in a quiescent state.
