The Alkaline Phosphatase is purified from calf intestine by a method developed in our laboratories, involving affinity chromatography. This enzyme is widely used as a marker enzyme in applications such as: • ELISA Immunoblotting Immunohistochemistry Molecular Biology Activity: >630 U*/mg enzyme protein (25°C, 4-nitrophenyl phosphate, glycine as buffer) • Unit definition: That amount of enzyme causing the hydrolysis of one mi…
The WellChampion™ preserves and protects biological activity of proteins and other biomolecules coated and dried on microwell surfaces. The protection of the coated and dried surface prevents degradation, denaturation and leaching. The WellChampion™ also efficiently blocks any free binding sites left on the microwell surface after coating, and a separate blocking step is avoided. Simply coat the microwell plate with the biomol…
The protein-free Blocking Buffer is a ready-to-use solution intended for blocking of the remaining free binding sites after microplate coating. The blocking is highly effective and stable. Our Synthetic Blocking Buffer™ eliminates the risk of false positive cross reactions in the assay. Current safety hazards related to the use of bovine material, for instance BSA are avoided. The buffer is ready-to-use and offers a high level…
The SamplePLUS is a 100% synthetic sample buffer for dilution of human or veterinary serum or plasma samples.The buffer efficiently minimizes cross-reactions, background and unspecific binding without inhibiting the specific binding.
The Sample Tracer is a 100% synthetic sample buffer for dilution of human or veterinary serum or plasma samples. The buffer efficiently minimizes cross-reactions, background and unspecific binding without inhibiting the specific binding. The Sample Tracer™ appears red, and when serum or plasma is added the Sample Tracer™ change colour to yellow. The buffer can detect serum or plasma in dilutions up to 1:100. If the advantage…
OPD, Ortho-Phenylenediamine, is used as a chromogen substrate in ELISA procedures with an absorption maximum at 492 nm and produces a yellow colour during the enzymatic degradation of hydrogen peroxide by horseradish peroxidase. After addition of sulfuric acid you will obtain a very stable end solution. The fizzing, buffer containing tablets are dissolved in distilled water within few minutes. This will give solution of pH 5.2…
