| Fast Green FCF Dye content ~90 % | Fast Green FCF dye is used for protein staining in IEF, native PAGE and SDS-PAGE. Fast Green staining is linear over a wider range of protein concentrations than Brilliant Blue R. After electrophoresis, fixing the proteins in the gel is recommended for maximum sensitivity. The gel can then be stained for 2 hr with 0.1% Fast Green FCF in either 30% (v/v) ethanol, 10% (v/v) acetic acid or in 7% acetic acid. The gel can be destained with either 30% (v/v) ethanol, 10% (v/v) acetic acid, or 7% acetic acid. The stained gel can be scanned at 625 nm. The detection sensitivity is approx. 30% that with Brilliant Blue R.

| Glycoprotein Detection Kit | The Glycoprotein Detection Kit is designed for the selective staining of glycoproteins on polyacrylamide gels and membranes using a modification of the Periodic Acid-Schiff (PAS) method.1 Staining of sugar moieties of glycoproteins yields magenta bands with a colorless background. The periodic acid/Schiff reagent stains vicinal diol groups found mainly on peripheral sugars and sialic acids and is used as a general glycoprotein stain.2

| Naphthol Blue Black for electrophoresis | Naphthol blue black dye can be used to stain proteins on polyacrylamide gels, agarose gels and nitrocellulose membranes. After electrophoresis, fixing the proteins in the gel is recommended. The gel can then be stained with 0.1% Naphthol Blue Black in 7% (v/v) acetic acid for at least 2 hr and destained with a soluion of 7% (v/v) acetic acid. Detection sensitivity is approx. 20% that of Coomassie Blue R.

| Oil Red O for electrophoresis | Oil Red O stain is suitable as a lipid/lipoprotein stain on cellulose acetate. A 0.2% stock solution is prepared in methanol. The stock solution (35 ml) is diluted with 10 mL of 1 M NaOH immediately before staining. The dye begins precipitating during staining. After staining (1 hr), the membrane is destained in methanol:glycerol (1:3). Often cited for use with agarose

| Periodic acid for electrophoresis, ≥99% | Periodic acid is commonly used as a component for glycoprotein stains1. Selective staining of glycoproteins on SDS-PAGE and membranes is carried out using a modification of the Periodic Acid-Schiff (PAS) method. Staining of sugar moieties of glycoproteins yields magenta bands with a colorless background. The Periodic Acid/Schiff Reagent stains vicinal diol groups found mainly on peripheral sugars and sialic acids and is used as a general glycoprotein stain2. Periodic acid is also used to cleave reversible cross-linkers (e.g. DATD, DHEBA) in PAGE gels.

| Ponceau S solution 0.1 % (w/v) in 5% acetic acid | Ponceau S stain comes ready-to-use and is designed for rapid (5 min) staining of protein bands on nitrocellulose or PVDF membranes (Western blots) and also for staining protein on cellulose acetate membranes. Ponceau S staining on nitrocellulose and PVDF is reversible by washing the stained membrane with 0.1 M NaOH for 1 min. The stained and destained membrane can then be immunologically detected (Western blotting). A product information sheet is supplied which includes the staining procedure for cellulose acetate, nitrocellulose, and PVDF.

| Reversible Protein Detection Kit for Membranes and Polyacrylamide Gels | R-PROB is a unique protein detection system designed for staining of proteins on nylon, nitrocellulose, and PVDF membranes or PAGE gels with the detection sensitivity similar to that of Coomassie stains. Most other stains produce high backgrounds on nylon membranes due to strong charge interactions with the membrane. The mixing of equal amounts of Solution A and B activates the stain, which produces lavender stained protein bands. The staining is easily reversible with an EDTA solution so that the blot can be reused for Western blotting or for amino acid sequence analysis (PVDF). R-PROB does not contain the toxic chemicals cacodylic acid or potassium ferrocyanide.

| Stains-All ~95% | Stains-all is suitable for differential staining of nucleic acids and proteins as follows; RNA (bluish purple), DNA (blue) and proteins (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.
