Synonyms3,3ʹ,5,5ʹ-Tetramethylbenzidine
DescriptionInsoluble TMB substrate supplied as a single component system. TMB is the most sensitive chromogenic substrate for detection of horseradish peroxidase (HRP)-labeled probes. In the presence of HRP and hydrogen peroxide (H2O2), TMB is oxidized first to a blue, cation free radical; upon further reaction with HRP/H2O2, or addition of acid, the radical is converted to a yellow diimine terminal oxidation product. TMB is used routinely in ELISA procedures, whereby its soluble oxidation products are measured spectrophotometrically. For TMB to be worthwhile as a blotting reagent, enhancers such as dextran sulfate or other sugar polymers are usually added.This TMB reagent is a safe, single component system that has been developed for use in blotting procedures by a proprietary methodology that eliminates the use of sugar polymers. The reagent produces a stable, insoluble aquamarine precipitate at the reaction site with little or no background. It can significantly increase the detection limits of assays on a variety of membranes. Ideal for many immunoblotting procedures and can significantly increase detection limits of assays on a variety of membranes

Recommended reaction conditionsSuggested Procedure for Immunoblot Staining with TMB: 1. Complete all required incubations with antibodies and HRP-labeled probes. 2. Wash membranes thoroughly with phosphate-buffered saline (PBS) or Tris-buffered saline (TBS), containing 0.1% Tween®-20 detergent. Note: Do not use reagents containing thimerosal or phenolic compounds as preservatives. 3. Following the final wash, cover the membranes completely with TMB solution and incubate with gentle rocking for 5-30 min, or until the desired color intensity is obtained (aquamarine/blue bands or dots will appear at the sites of enzyme activity). Note: Variables associated with assay conditions will dictate the proper reaction time. If the color develops immediately, the TMB precipitate may flake off the membrane. If this occurs, further dilution of the HRP probe is recommended. A fine blue line circumscribing the band or dot also suggests that dilution of the enzyme is necessary. 4. Stop the reaction by washing the membrane thoroughly in distilled water. DO NOT WASH WITH BUFFERED SOLUTIONS OR TAP WATER. These will cause fading. Also, DO NOT USE ACIDS TO STOP THE REACTION. Acids will turn the bands yellow. Excessive background staining indicates incomplete removal of unbound HRP from membranes. To remedy this problem, increase the wash steps or washing times. 5. Air-dry membranes and store protected from light.
