The Spermine ELISA Kit is a highly sensitive and specific assay designed for the accurate detection of spermine levels in various biological samples. This kit is ideal for researchers studying the role of spermine in biological processes such as cell growth, metabolism, and gene expression. Spermine is a polyamine compound that plays a critical role in cell proliferation, DNA stabilization, and cell signaling. Abnormal levels of spermine have been linked to various diseases, including cancer, neurodegenerative disorders, and metabolic syndromes.
The Spermine ELISA Kit provides researchers with a reliable tool to study the impact of spermine on disease progression and potential therapeutic interventions. Key features of the Spermine ELISA Kit include high sensitivity, specificity, and reproducibility, allowing for accurate quantification of spermine levels in serum, plasma, and tissue samples. This kit is essential for researchers seeking to elucidate the biological functions of spermine and its implications in disease pathogenesis.

Note: The below protocol is a sample protocol. Protocols are specific to each batch/lot. For the correct instructions please follow the protocol included in your kit.
Step
Procedure
1
Reagent & Plate Preparation: Equilibrate TMB substrate for 30 minutes at room temperature. Prepare standards, samples (minimum 1:2 dilution), blanks, assign wells, and pre-wash the plate twice.
2
Sample & Biotin-Antibody Binding: Add 50 µL standard or sample followed by 50 µL biotin-labeled antibody to each well. Mix gently and incubate at 37°C for 45 minutes.
3
Washing: Wash the plate 5 times with wash buffer, allowing 1 minute soak time per wash.
4
Color Development: Add TMB substrate and incubate in the dark at 37°C for 10-20 minutes until color develops.
5
Stop Reaction: Add stop solution to terminate the reaction. The color changes from blue to yellow immediately.
6
Reading: Measure absorbance at 450 nm using a microplate reader.
