Do not store together with: Oxidizing agent. 4. Contaminated or leaked out substrate solution from damaged bottles should not be used anymore and has to be destroyed.5. Use isolated containers with some cool bags for transport.6. Spontaneous decay will increase the background. If stored at room temperature, the velocity of the decay will increase. Thus, both storage and transport at room temperature should be avoided. Nevertheless, the activity of the solution is not affected by storage at room temperature. The solution still works beyond the expiry date, but some applications, especially those including visual evaluation, may be hampered by increased background. 3、Effective Components and Principle of FunctionIn different buffer solutions (pH = 9.5), with supplementation if required, the effective componentpara nitrophenyl phosphate (pNPP) is dissolved. Alkaline Phosphatase transfers the phosphate residue to an acceptor. Under alkaline conditions a yellow colour occurs, resulting from the formed nitrophenol. 4、Biosafety informationThis mixture is not classified as hazardous in accordance with Regulation (EC) No 1272/2008； 5、Advantage1.

After substrate incubation the reaction can be stopped and the photometric measurement can be carried out. Using higher incubation temperatures (37° C) may shorten the incubation time. The reaction can be stopped by using the special developed solution stop. The use of other commercially available stop solutions cannot safely exclude a further increase of the signal. Addition of a stopping solution does not change the general shape of the spectrum. The unstopped and the stopped solution should be measured at 405 nm and the background correction: should be measured at 620 nm...

After the primary antibody of rabbit or mouse origin binds to the corresponding target antigen, the biotinylated antibody in this kit • • Rabbit/mouse universal secondary antibody specifically binds to the primary antibody; The biotin labeled on the secondary antibody binds to streptavidin labeled with peroxidase (HRP), forming an antigen-specific primary antibody biotinylated secondary antibody streptavidin complex labeled with HRP. HRP can catalyze substrate colorimetry, thereby inferring the presence and distribution of the tested antigen. The biotinylated secondary antibody and SA-HRP used in this reagent kit all adopt optimized labeling and purification techniques, which make their staining more sensitive and have a lower background. They are suitable for detecting formalin fixed paraffin embedded tissue sections, as well as frozen sections, cell slides, freshly prepared blood smears, etc. The rabbit/mouse universal Streptavidin HRP kit is suitable for use with aladdin ready to use or concentrated antibodies.
