The Human SEMA4D (Semaphorin 4D) Quickstep ELISA Kit is designed for the quantitative detection of Human SEMA4D (Semaphorin 4D) levels in various biological samples. Ampicillin (AP) is a broad-spectrum beta-lactam antibiotic belonging to the aminopenicillin class that inhibits bacterial cell wall synthesis by irreversibly binding to penicillin-binding proteins. It is widely used in veterinary medicine for treatment of bacterial infections in food-producing animals. Regulatory maximum residue limits for ampicillin in animal-derived food products have been established to protect consumers from adverse reactions and prevent selection for antimicrobial resistance. Sensitive immunoassay detection of ampicillin residues in food matrices is essential for food safety programs and veterinary drug surveillance. Assay Genie's Human SEMA4D (Semaphorin 4D) Quickstep ELISA Kit offers exceptional sensitivity and specificity with a sensitivity of 2.34 ng/mL, ensuring reliable and reproducible results across a broad range of sample types including serum, plasma and other biological fluids. Manufactured under stringent quality control standards, this ELISA kit provides robust performance and ease of use, making it an outstanding choice for both research and clinical applications. Trust Assay Genie's Human SEMA4D (Semaphorin 4D) Quickstep ELISA Kit for accurate and dependable quantification of this crucial biomarker in your studies.

This ELISA kit uses the Sandwich-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to the target protein. Standards or samples are added to the micro ELISA plate wells and bind to the immobilized antibody. A biotinylated detection antibody specific to the target protein is then added, followed by Avidin-Horseradish Peroxidase (HRP) conjugate. Free components are washed away. The substrate solution is added to each well, resulting in a color change. Only wells containing the target protein, detection antibody, and HRP conjugate will develop a blue color. The reaction is terminated by the addition of stop solution, resulting in a yellow color. The optical density (OD) is measured at 450 nm ± 2 nm. The OD value is directly proportional to the concentration of the target protein in the sample and is determined using a standard curve.
