Mouse Isotype control has been prepared from concentrated cell culture supernatant by immunoaffinity chromatography using protein A. Assay by immunoelectrophoresis resulted in a single precipitin arc against anti-Mouse IgM mu and anti-Mouse serum. Isotyping assay resulted non-reactive with antisera to mouse IgG1, IgG2a, IgG2b, Ig3, IgA. Light chain composition has been confirmed by SDS-PAGE.
Form:
Liquid (sterile filtered)
Application Dilute:
FC: 1:1000-1:5000
Application Notes:
Biological Origin: Mouse. Application Notes: Mouse IgM lambda isotype control has been tested in SDS-Page and can be utilized as a control or standard reagent in Flow cytometry, Western Blotting, and ELISA experiments where determination of sample isotype is important
