| Description | AP-StabilPLUS is used for the dilution and stabilization of Alkaline Phosphatase (AP) labeled proteins and antibodies, in order to maintain the molecular conformation and prevent loss of activity over time. This enables the making of prediluted, ready-to-use AP-conjugates, minimizing assay errors inAP-StabilPLUS is used for the dilution and stabilization of Alkaline Phosphatase (AP) labeled proteins and antibodies, in order to maintain the molecular conformation and prevent loss of activity over time. This enables the making of prediluted, ready-to-use AP-conjugates, minimizing assay errors in dilution.Stabilization of AP conjugated antibodies in low as well as high protein dilutions is seen, when using AP-StabilPLUS. When tested with AP conjugated antibody stability is seen as follows:at least 3 years at 2-8 °Cat least 2 years at room temperatureat least 4 weeks at 37 °CProduct Characteristics AP-StabilPLUS is used for the dilution and stabilization of Alkaline Phosphatase (AP) labeled proteins and antibodies, in order to maintain the molecular conformation and prevent loss of activity over time. This enables the making of prediluted, ready-to-use AP-conjugates, minimizing assay errors in dilution.When testing the AP-StabilPLUS with AP conjugated antibodies, stability is seen as follows: • at least 3 years at 2-8 °C • at least 2 years at room temperature • at least 4 weeks at 37 °C Stabilization of AP conjugated antibodies works well in low as well as in high protein dilutions.Composition & Properties AP-StabilPLUS is a ready-to use buffer that appears as an opaque solution. The product is based on a mild Tris buffer containing proprietary stabilizing components. AP-StabilPLUS contains neither BSA, nor other material from bovine serum, azide, mercury or other toxic components.Working Procedure 1.Make a series of dilutions of the AP-conjugated protein in AP-StabilPLUS in order to determine the optimal dilution. 2.Run the assay as usual or store the diluted APconjugated protein preferably at 2-8 °C.Tips & Tricks • Avoid using phosphate buffers for AP-conjugated antibody assays. We recommend the use of Tris/HCl, Tween as the washing buffer, instead of a PBS buffer which will reduce signal significantly.Handling & Storage • Store solution at 2-8 °C...

A stable blue precipitate is formed at the reaction site. The substrate does not contain NMP (1-methyl-2- pyrrolidone) making it REACH Restricted Substances List Annex XVII compliant, while ensuring maximal safety during use, and minimal waste problems after use.Composition & Properties Ready-to-use substrate: Includes substrate buffer and hydrogen peroxide. No other reagents should be added.Working Procedure The following procedure is applicable to nitrocellulose membranes. The procedure must be optimized for other membranes.1.The desired amount of substrate is poured into a sealed container and allowed to reach room temperature, in the dark, before use. 2.After the last incubation with HRP-labelled Streptavidin or HRP-labelled secondary antibody it is recommended to wash the membrane in a 0.1 M Tris buffer pH 7.4.3.Shake off the excess buffer and incubate the membrane in the TMB-D Blotting solution for 10 minutes. 4.Wash the membrane in distilled water and allow it to dry. 5.The site of positive reaction will appear light blue with no or very little background staining.Tips & Tricks • The membrane can be blocked with Kementec’s Synthetic Blocking Buffer for Blotting, (cat. no. S494457). • For long-term preservation of the results, the membranes must be stored in the dark.Handling & Storage • Store solution at 2-8⁰C in the dark. • Avoid exposure to light, heat and contamination with metal ions or peroxidase. • Re-dispense only into bottles made of High-Density Polyethylene (HDPE), amber color.
