Reagent storage and disposal

What are the shipping conditions for Cytocell products?

Shipping temperatures are dependent on both the product and the destination.

1. Aquarius and Multiprobe probe products shipped within the EU are shipped at ambient temperature.

2. Aquarius and Multiprobe probe products shipped outside the EU are shipped at 4°C with an ice pack.

3. Tissue Pretreatment kits are shipped at 4°C.

What are the storage conditions for Cytocell products?

1. Storage temperatures are dependent on the product.

2. On receipt of the products at the laboratory Aquarius probes should be stored between -15°C to -25°C. The Multiprobe products should not be frozen and should be stored at 2-8°C.

3. Tissue Pretreatment kits are stored at 2-8°C.

‘We have some expired Aquarius probes that require disposing. Can you recommend the best practice for FISH probe disposal?’

We would suggest that you dispose of your unwanted probes by throwing them in the general lab waste; treating the probes as you would any other low-grade hazardous waste. Please note that the probes should not be flushed down a drain.

Why do the reagent lot numbers differ from the kit number?

The number provided on the kit is the kit lot number. The individual component(s) in the kit will also have their own lot numbers specific for the manufacture of those products.

‘We suspected that the FISH probe is light damaged. How can we identify this problem? What advice can you offer to minimise this effect?'

Please inform Cytocell technical support if you suspect that your probe is showing signs of light damage. In addition, we keep a probe archive retain, which we will test internally. The common characteristics of light damaged probes are nonspecific probe binding and high autofluorescence.

To mitigate the effects of light damage, we recommend the following:

- Reduce the level of probe exposure. Cover probe, place in -20°C freezer when not in use.

- Aliquot probe on arrival into single use ‘shots’.
