Coomassie Stains

Overview

Bio-Safe Coomassie Stain

Protein stained with Bio-Safe Coomassie stain. Gel contains SDS-PAGE low range standards (lanes 1, 8), human transferrin (lanes 2, 3), fish lysate (lanes 4, 5), and E. coli lysate (lanes 6, 7).

Configuration

Bio-Safe Coomassie Configuration

Bio-Safe Coomassie stain is available in a 1 L bottle or a 5 L cube.

2-D Gel

2-D after Bio-Safe Coomassie Stain

2-D gel stained with Bio-Safe Coomassie stain.First dimension: 300 µg of E. coli lysate treated with RNase and DNase in rehydration buffer containing 0.1% Bio-Lyte ampholytes was loaded onto a 17 cm ReadyStrip IPG strip (pH 4–7) and focused 92,000 V-hr on the PROTEAN IEF cell. Second dimension: The strip was loaded onto a 20 x 20.5 cm PROTEAN Plus 8–16% gel, and run at 200 V constant for 6 hr.

Coomassie blue dyes are a family of dyes commonly used to stain proteins in SDS-PAGE gels. The gels are soaked in dye, and excess stain is then eluted with a solvent ("destaining"). This treatment allows the visualization of proteins as blue bands on a clear background. Bio-Rad offers Coomassie stains in four formats.

QC Colloidal Coomassie (161-0803) — the newest in the family of Bio-Rad Coomassie stains, QC Colloidal Coomassie G-250 allows for flexible staining and destaining times and does not require use of methanol for fixing.

Low background, high sensitivity, superior reproducibility
Environmentally friendly formulation — no addition of methanol or acetic acid required; eliminates the need for hazardous waste disposal
Flexible staining and destaining times — from 1 hour to overnight
No alcohol addition or dilution steps when staining polyacrylamide gels
One-part, ready-to-use colloidal Coomassie stain

Bio-Safe™ Coomassie (161-0786) — Bio-Safe Coomassie Brilliant Blue G-250 stain is fast, simple, sensitive, and convenient.

Premixed, ready-to-use, nonhazardous solution
No methanol or acetic acid required for destaining
Bio-Safe composition reduces solvent waste disposal costs

Coomassie Brilliant Blue R-250 (161-0436) — Coomassie Brilliant Blue R-250 staining solution is the fastest and easiest way to Coomassie-stain Criterion™ precast gels or other polyacrylamide protein gels.

Coomassie Reagents — Coomassie Brilliant Blue R-250 and G-250 powders are available in 10 gram vials.

Coomassie G-250 (161-0406) is more sensitive
Coomassie R-250 (161-0400) provides better resolution and lower cost

The catalog number, SKU number, or product number is printed on your product label. See the sample label below for the location of this information.

Where can I find the lot or control number?

The lot number or control number (one or the other, not both) is printed on your product label. See the sample label below for the location of this information.

Why are Certificates of Analysis not on the Documents tab?

Certificates of Analysis are associated not only with a product, but also with a specific lot of that product. For a given product, there may be several Certificates of Analysis, especially if it is an older product line and has had several lots produced over the years. Using the Certificate of Analysis search tool, you can enter the catalog number and lot/control number for the specific product you have on hand and download the exact Certificate of Analysis you need.

I have a batch number, not a lot/control number. How do I find the Certificate of Analysis for my item?

You can use the batch number in place of the lot/control number. Use the Certificate of Analysis search tool, entering the catalog number as usual and the batch number where the lot/control number would go.

Can I get a Certificate of Analysis even if my item is expired?

Yes. While we do periodically remove Certificates of Analysis for site maintenance purposes, we typically keep them available well beyond a product's expiration date.

Why does it say "Product Name Not Found" for a Certificate of Analysis listed in the search results?

There are Certificates of Analysis that correspond to products that are either discontinued or simply not available on the website. In these situations, the Certificate of Analysis is available for download, but other product details, such as the product name, are not.

Why does it say "Not Available" for a Certificate of Analysis listed in the search results?

In this case, you have entered a valid catalog number and lot/control number and we have located the Certificate of Analysis. However, for some reason, the actual file itself is unavailable.

Please use the Request Form here or contact your local Bio-Rad Representative so that we can send you the Certificate of Analysis.
