If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.

General description
Widely utilized in cell biology and biochemical research, HEPES proves its versatility in protein purification and extraction protocols, owing to its stability across a broad pH range and minimal metal ion binding. Additionally, HEPES proves valuable in various biological and biochemical processes, including immunoprecipitation, cell lysis, and live cell imaging, making it a versatile tool in diverse research applications.
Application
- Most studies with metal ions
- Substitute for Tris and phosphate in studies with metal ions
- Grinding buffer in plant studies
- Running buffer in gel electrophoresis
- Buffer in electroporation studies
- Bradford or bicinchoninic acid (BCA) assays
- Extraction buffer to prevent damage of proteins in red blood cells
It has been used:
Features and Benefits
- Tested to confirm low levels of heavy metal contamination, ensuring suitability for various applications
- Highly soluble in water
- Negligible metal ion binding
- Less toxic to cells than other buffers such as Tris and phosphate
- Stable in a wide pH range
Packaging
- The current DRYPOUR® packaging configuration is in a 50L nestable drum
- 25KG-DP are the standard prepack offering
- Smaller volumes can be put in the same drum for variable configurations
- Improves operational efficiency by reducing material preparation time and increasing operator safety
- Minimizes caking of hygroscopic salts
- Offers triple protection: against moisture inside and outside, and against contamination
- This state-of-the-art design packaging system minimizes caking, thus significantly reducing the time needed for material preparation
- PE drum with our new tamper-evident seal, a polyethylene liner with integrated desiccant bags and a breathable interior Tyvek® liner
- Desiccant bags are firmly integrated into the polyethylene liner
- Triple protection delivers two invaluable results:
- Dramatically reduced caking
- No contamination risk from the desiccant

How is shipping temperature determined? And how is it related to the product storage temperature?
1 answer-
Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf
