Stain-All *CAS 7423-31-6*
Stains-all is suitable for differential staining of nucleic acids and proteins. It stains RNA on bluish purple, DNA in blue and proteins in red. As little as 3 ng (123 BP fragment) of pBR322/Hae III digest DNA and 90 ng tRNA can be detected on a polyacrylamide gel. PAGE gels are stained in the dark and then destaining by removing the gel from the staining solution and exposing it to the light from a light box until sufficient destaining has occurred. A staining solution is typically made by dissolving the dye in formamide and buffer.
Example protocol
AT A GLANCE
Important
Store at -20 °C. Expiration date is one year from the date of receipt.
Maximum Excitation: 573 nm
Maximum Emission: 609 nm
PREPARATION OF STOCK SOLUTION
Unless otherwise noted, all unused stock solutions should be divided into single-use aliquots and stored at -20 °C after preparation. Avoid repeated freeze-thaw cycles.
1. 0.1% Stains-All stock stain:
Add 10 mg of Stains-All into 10 mL of formamide and mix well.
PREPARATION OF WORKING SOLUTION
Stains-All working solution:
Mix 1 mL stock stain, 1 mL formamide, 5 mL isopropranol, 100 μL Tris-HCl (3.0 M, pH-8.8) and 12.9 mL water, Mix well.
SAMPLE EXPERIMENTAL PROTOCOL
Table 1. Stain colors of different biomolecules with Stain-All
| Biomolecule | Stain Color |
| RNA | Bluish Purple |
| DNA | Blue |
| Proteins | Red |
| Acid Mucopolysaccarides | Various |
Gel Electrophoresis
- Stain gel by soaking it in a covered container for 18 to 24 hours, protected from light.
- Destain the gel by soaking it in water, protected from light. Note: Exposure to light will produce a dull yellow background. Note: Destaining may also be done by exposing the gel to light for 30 minutes.
