Pro-Detect™ 快速抗体分型检测试剂盒（人）

The Thermo Scientific Pro-Detect Rapid Antibody Isotyping Assay Kit - Human is a single-use, dipstick lateral flow kit for quick, easy determination of rat monoclonal antibody class and subclass identity. This antibody isotyping assay uses membrane-based strips coated with dye-bound conjugated antibodies that provide a visual, color readout of the monoclonal antibody isotype within ten minutes. The kit determines human IgG1, IgG2, IgG3, IgG4, IgA, IgM, as well as light-chain identity (kappa vs. lambda light chains).

Features of the Pro-Detect Rapid Antibody Isotyping Assay Kit:
• Long shelf life—stable for at least one year at 4°C
• Simple workflow—dilute antibody sample using provided diluent and dip in the lateral flow strip
• Fast—within 5–10 minutes a band appears that indicates the antibody isotype
• Sensitive—detect antibodies in tissue culture media or ascites fluid samples down to low ng/mL concentrations
• Specific—assay does not cross-react with fetal bovine serum (FBS)
• Reliable—results are similar to standard ELISA-based isotyping assays

Each Pro-Detect Rapid Antibody Isotyping assay is performed by simply adding a properly diluted tissue culture supernatant or mouse ascites sample to a test tube or microplate well and dipping in a lateral flow strip. Gold conjugates embedded in the strip membrane form specific class- and subclass-soluble complexes with the antibodies in the sample. These complexes travel the length of the membrane and are resolved on the anti-isotype and class-specific antibody-impregnated regions of the membrane. Results are displayed as a red band above the printed class or sub-class description, indicating the antibody isotype present.

Determining the class and subclass of a human antibody is important in a variety of research areas including infectious disease, cancer, autoimmune diseases, immunodeficiency disorders, and drug and vaccine development. Isotyping is also important when developing and purifying humanized antibodies.

The Pro-Detect Rapid Antibody Isotyping Assay Kit is compatible with both tissue culture supernatant and mouse ascites fluid, and is more sensitive than conventional latex bead-based dipstick assays and much faster than ELISA-based isotyping assays. The kit requires only 2–22 μL of cell culture supernatant.
