What is the pore size of Pall Biodyne B Nylon
Membrane?
The pore size of this membrane used with the OmniTray is 0.45 µm.
Is the Pall Biodyne B Nylon Membrane sterile?
No, this membrane is not supplied sterile, even though the OmniTray is sterile.
When screening DNA libraries, how much Agar is added
the the OmniTray?
The OmniTray can hold 35 ml of growth media. 1.5% agar is recommended to be
added to the growth media. See Tech Note Vol. 3 No. 21.
Does Nunc have a square Petri dish with a grid on the

When performing an in situ hybridization using
NucleoLink Strips, what are the detection methods?
The detection methods for this type of experiment can be fluorometric,
colorimetric or use of a radioactive probe.
What is the "shelf-life" of NucleoLink
Strips stored in a sealed ethylene bag at 4°C?
Uncoated NucleoLink Strips are stable for at least three years if the original
packing is intact. After "coating" the strips with an oligonucleotide
probe, we generally store the strips in a sealed ethylene bag at 4°C. The
stability may vary with the probe composition. NucleoLink Strips are stored in a
sealed bag at 4°C and are stable for at least 10 months.
Is EDAC the same compound as EDC?
Yes, both acronyms are used for the same compound. The chemical name for EDC is
1-ethyl-3-(3-dimethylaminopropyl)-carbodiimide and the chemical name for EDAC is
N-3-(3-dimethylaminopropyl)-N-ethyl-carbodiimide. Both of these compounds are
structurally equivalent.
Does Nunc have 96-well plates with snap-on lids
which lock to prevent evaporation?
No, Nunc MicroWell polystyrene plates are sold individually or in a sleeve of 5
without lids. However, we do have accessories for these plates which include
lids that loosely cover the plate and adhesive tape that covers the entire 86 x
128 mm plate.
Does the 384 Well Plate autofluoresce?
The 384 Well Plate is made of a select, crystalline polystyrene which exhibits
minimal autofluorescence.
Does Nunc sell 0.2 ml tubes to be used for
amplification or PCR?
Yes, our GeNunc tubes are sold as individual tubes or as 1 x 8 strips and each
have a 0.2 ml volume. These tubes are RNase and DNase free. The following table
