Antibody application notes

For coating for ELISA, order Ab without BSA, Higher concentration may be required for direct detection using primary antibody conjugates than for indirect detection with secondary antibody, Optimal dilution and staining procedure for a specific application should be determined by user, Recommended starting concentrations for titration are 1-2 ug/mL for most applications, or 1 ug/million cells/100 uL for flow cytometry

Product Description

This is a non-reactive mouse monoclonal IgG2a kappa antibody labeled with one of our bright and photostable CF® Dyes and other labels. This antibody may serve as a control for a mouse monoclonal IgG2a antibody under identical experimental conditions. Biotium also carries mouse monoclonal isotype control antibodies for IgG1 Kappa (IGG1/1331) and IgG2b Kappa (IGG1/1333).

  • Isotype control for antibody-based experiments
  • Available with 6 bright and photostable CF® Dyes and biotin
  • Suitable for western, flow cytometry, ELISA, immunofluorescence,  and immunohistology
