Zeocin® | Selection antibiotic: endotoxin tested, sterile reagent
InvivoGen is the sole worldwide producer of Zeocin®.
Zeocin® is a formulation of phleomycin D1, a copper-chelated glycopeptide antibiotic produced by a proprietary strain Streptomyces CL990. Zeocin® causes cell death by intercalating into DNA and cleaving it.
The action of Zeocin® is effective on most aerobic cells. Therefore, Zeocin® is a popular and effective antibiotic for the selection of vectors bearing the Sh ble gene in a variety of cells types (bacteria, eukaryotic microorganisms, plant and animal cells).
Resistance to Zeocin® is conferred by the Sh ble gene product from Streptoalloteichus hindustanus, which inactivates Zeocin® upon binding to the antibiotic [1-3].
Sh ble is a small 370bp-sized gene and is carried in a number of InvivoGen’s vectors.
Typically, mammalian cells are sensitive to Zeocin® concentrations of 50-400 µg/ml, and bacteria to 25 µg/ml.

Is the Zeocin® you provide hydrochloric or sulfate?
We supply hydrochloric Zeocin®.
Is Zeocin® photosensitive?
No, Zeocin® is not photosensitive.
Is Zeocin® pH sensitive?
Zeocin® will undergo irreversible denaturation at a low and high pH (<6 and >8) or in the presence of a weak oxidant.
What buffer can be used to dilute Zeocin® to make intermediate working solutions?
Further dilutions should be performed in sterile water to create an intermediate working solution.
What is the concentration of HEPES buffer used to reconstitute Zeocin®?
The concentration of HEPES buffer used to reconstitute Zeocin® is 5 g/L.
What is the preferred storage method for Zeocin®?
Zeocin® is shipped at room temperature. Upon receipt, it should be stored at 4°C for short term storage or -20°C for long term storage.
Avoid repeated freeze-thaw cycles.
The expiry date is specified on the product label.
For Zeocin® powder, once resuspended at 100 mg/ml, it can be stored at 4°C for 12 months or -20 °C for 18 months.
For Zeocin® solution, once opened it remains stable for 1 year at -20°C providing you avoid repeated freeze-thaw cycles, and it can be kept at 4°C for 3 months provided it is kept in sterile conditions.
What is the selection concentration of Zeocin® in mammalian cells?
The working concentration of Zeocin® in mammalian cell lines varies between 50 - 400 μg/ml, with a few reported cases of its use at lower (i.e. 20 μg/ml) and higher (i.e. 1000 μg/ml) concentrations. In an initial experiment we recommend to determine the optimal concentration of Zeocin® required to kill your host cell line. For more detailed information, please refer to the technical data sheet for this product.
What is the selection concentration of Zeocin® in E. coli?
Zeocin-resistant transformants are selected in low salt LB agar supplemented with 25 μg/ml of Zeocin®.
Important: Do not use an E. coli recipient strain that contains the Tn5 transposable element (i.e. MC1066). Tn5 encodes a bleomycin-resistance gene that will confer resistance to Zeocin®.
