The LXB4 (Lipoxin B4) ELISA Kit is a powerful tool for measuring levels of Lipoxin B4 in various biological samples such as serum, plasma, and tissue homogenates. With its high sensitivity and specificity, this kit provides accurate and reliable results for research purposes. Lipoxin B4 is a potent lipid mediator that plays a key role in inflammation resolution and immune regulation. It is involved in processes such as the recruitment of immune cells to sites of injury or infection, as well as the modulation of inflammatory responses.
Dysregulation of Lipoxin B4 levels has been linked to various inflammatory diseases, making it a valuable biomarker for studying these conditions and developing potential therapeutic interventions. Overall, the LXB4 ELISA Kit is an essential tool for researchers studying inflammation, immune regulation, and related diseases. Its user-friendly design and robust performance make it a valuable asset for any laboratory conducting research in this field.

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.
