Store at 28°C

When stored at 28°C, UltraWash™ PBS is stable for a minimum of 3 years from the manufactured date. The working solution should be clear and colorless in appearance.

UltraWash™ PBS 10X Concentrate contains 0.5% Tween 20 which has no net charge, preventing interaction with immunoassay reagents and solid surfaces.

Reduce Background – Reduces nonspecific binding by reducing unstable hydrophobic bonds between immunoassay reagents.
Extended Shelf Life – UltraWash™ PBS is stable for a minimum of 3 years from the date of manufacture when stored at 2° 8°C.
Ease of Use – Simply add 1 part UltraWash™ PBS to 9 parts high purity deionized water. Following dilution, the buffer is ready to use.

Preparation: Add 1 part UltraWash™ PBS to 9 parts high purity deionized water and mix well. Allow working solution to equilibrate to room temperature (25°C) prior to use. To minimize the risk of contamination a fresh working solution should be made each day. If aseptic technique is used during preparation, unused working solutions may be stored at 2° 8°C.
Use: Cover target surface and treat for several minutes. Aspirate or dump solution and repeat the wash step as necessary. Wash times should be optimized by each investigator for their specific applications.
