How to Find a Lot/Batch Number for COA
Lot and Batch Numbers can be found on a product's label following the words 'Lot' or 'Batch'.
Aldrich Products
For a lot number such as TO09019TO, enter it as 09019TO (without the first two letters 'TO').
For a lot number with a filling-code such as 05427ES-021, enter it as 05427ES (without the filling-code '-021').
For a lot number with a filling-code such as STBB0728K9, enter it as STBB0728 without the filling-code 'K9'.
Not Finding What You Are Looking For?
In some cases, a COA may not be available online. If your search was unable to find the COA you can request one.
How does the storage temperature relate to shipping conditions?
The storage conditions that a Sigma-Aldrich catalog and label recommend for products are deliberately conservative. For many products, long-term storage at low temperatures will increase the time during which they are expected to remain in specification and therefore are labeled accordingly. Where short-term storage, shipping time frame, or exposure to conditions other than those recommended for long-term storage will not affect product quality, Sigma-Aldrich will ship at ambient temperature. The products sensitive to short-term exposure to conditions other than their recommended long-term storage are shipped on wet or dry ice. Ambient temperature shipping helps to control shipping costs for our customers. At any time, our customers can request wet- or dry-ice shipment, but the special handling is at customer expense if our product history indicates that the product is stable for regular shipment. See Shipping and Storage for more information.
Which document(s) contains shelf-life or expiration date information for a given product?
If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.
How do I get lot-specific information or a Certificate of Analysis?
The lot specific COA document can be found by entering the lot number above under the "Documents" section.

Why is DAPI (4´,6-Diamidino-2-phenylindole dihydrochloride ) added to Fluoroshield with DAPI mounting media, Product No. F6057?
This mounting medium is fortified with DAPI which is a counter-stain for DNA. This product is to be used in situ hybridization techniques or other methods where fluorescence of DNA staining is required. DAPI excites at 360 nm and emits at 460 nm, producing a blue fluorescence. RNA is also stained with DAPI.
How do I store Fluoroshield (Product Nos. F6182, F5932, F6057) ?
This product is stored at 2-8°C. Protect from light, and do not freeze.
How do I use Fluoroshield (Product Nos. F6182, F5932, F6057)?
1. Bring the vial to room temperature. 2. Rinse slide to be mounted with DISTILLED OR DEIONIZED WATER, then touch the edges of slide on a paper towel to remove excess water. Place slides on a flat surface away from light. 3. Turn the vial upside down and remove any air bubbles. 4. Apply 3-4 drops directly of mounting medium on top of the specimen and spread out evenly by tilting the slide back and forth or spread evenly with a 0.2 ml plastic pipette tip, making sure the tissue is not touched. Excess medium can be removed by touching the edges of slide on paper towel. 5. Let stand at room temperature for about 5 minutes. 6. Apply cover slip, carefully avoiding air bubbles. 7. The specimen is ready for visualization under microscope. 8. One can seal the edges of cover slip with nail polish or any organic medium. If coverslip is not used air bubbles will appear in few days. 9. For long term storage it is recommended that the slide be stored in the dark at 2-8°C.
How do you remove the coverslip when using Fluoroshield (Product Nos. F6182, F5932, F6057)?
The coverslip can be removed before sealing the edges. Soak slide in warm (37 °C) water for a few minutes. Carefully and slowly move the coverslip. Soak in water for an additional few minutes to remove coverslip. Rinse slide several times with warm water to remove all mounting medium. The slide can be remounted again.
What fluorochromes can be used with Fluoroshield (Product Nos. F6182, F5932, F6057)?
This unique formula prevents rapid photobleaching of FITC, Texas Red®, AMCA, Cy®2, Cy®3, Cy®5, Alexa Fluor® 488, Alexa Fluor® 594, green fluorescent protein (GFP), tetramethylrhodamine, R-phycoerythrin (R-PE), phycocyanin (PC), and allophycocyanin (APC). Fluorescence is retained during prolonged storage at 4°C in the dark. This medium does not contain phenylenediamine, which destroys immunofluorescence of the Cy dyes, RP-E, PC and APC.
Does Fluoroshield (Product Nos. F6182, F5932, F6057) contain an antifade reagent?
This unique formula prevents rapid photobleaching. The exact nature of the antifade is considered proprietary.

The Human Protein Atlas Program has carefully selected three different human cell lines, A-431 epidermoid carcinoma, U-251 MG glioblastoma and U-205 osteosarcoma, for organelle mapping of the proteome. As Prestige Antibodies are studied by immunofluorescence (IF) staining, three well-characterized organelle markers for nuclei, microtubules and endoplasmic reticulum are used correspondingly as specific probes. The high-resolution confocal images are annotated based on sub-cellular localization. In addition, staining intensity and characteristics are also part of an overall assessment as well as comparison to literature (if available).
