We ship products at different temperatures depending on how sensitive they are to heat.
If the ice pack is thawed and the temperature inside the box rises to greater than 4°C, please be assured that this should not affect the product's stability. The antibodies are sufficient to use if you store them correctly upon receipt.
We ship all products at temperatures they are known to be stable at, but it's critical to store them as directed by the datasheet upon arrival. The best conditions for long-term product stability can differ from the optimal short-term conditions we use during shipping.
If you have any trouble with a delivered product, please contact us; our HUABIO guarantee covers all of our products.
