Cyanine 555 Tyramide

Coelenterazines are predominantly yellow solids, but may contain dark red or brown flecks. This does not affect product stability or performance. If your coelenterazine is uniformly brown, then it is oxidized and needs to be replaced.

Most of our products are stable at room temperature for many days, but we recommend storage at 4°C or -20°C to prolong shelf life. In the case of many of our aqueous dye solutions, the compounds are very stable at room temperature, but we recommend cold storage to prevent the growth of mold or other microbes over time. Therefore, to save on shipping costs, products with recommended storage at 4°C or -20°C may ship at ambient temperature or with an ice pack. These products may thaw without affecting product performance. When you receive the product, place it under the recommended storage conditions.

Biotium ships all antibodies (primary, secondary and conjugates) at room temperature. We guarantee their quality and performance under these conditions based upon our stability testing. Antibodies were subjected to accelerated stability testing by storing them at various temperatures (4°C, room temperature, or 37°C) for 1 week to mimic simulated shipping conditions and tested in immunostaining experiments. All antibodies showed the expected brightness and specificity, even after storage at sub-optimal temperatures.

In line with our goal to be more environmentally friendly by reducing the use of excess packaging, and lowering shipping costs for our customers, products that have passed our stability testing are shipped at room temperature.

Once you have received the antibody vial, please follow the long-term storage instructions on the product information (PI) sheet.
