Q&A

Where can SDS be downloaded?​
You can download it from the following URL.​
Safety Data Sheet (SDS)
Is the extract (lyophilized product) dissolved in purified water?​
Yes, it becomes a clear solution when dissolved in purified water. However, it may become slightly cloudy. The dissolved solution is phosphate-buffered saline (PBS, pH 7.4).​
Why do you filter the extracts during the manufacturing process?​
The purpose of the filtration depends on the size of the pores in the filter used. The 0.8 µm and 0.45 µm filters are used to remove impurities (0.8 µm is used for pollen extracts, 0.45 µm is used for other extracts), and the 0.2 µm pores are used to filter out microorganisms and other minute particles such as sediment.​
Does the preservative in the extract have any effect on the ELISA measurement system?​
We add Proclin® 950 as a preservative, but it does not affect the enzymes used in normal ELISA kits.​
For products that do not specify allergen or total protein concentrations, is it possible to ask for this information?​
Yes, but there will be an additional charge for the measurement and a separate delivery date.​
