Cat.No.224204 | 100 µl antiserum, lyophilized. For reconstitution add 100µlH2O, then aliquot and store at -20°C until use. |
Applications | WB:1 : 1000 up to 1 : 2000 (AP staining)(see remarks) galleryIP:not tested yetICC:1 : 200 up to 1 : 1000(see remarks) galleryIHC:1 : 500(see remarks) galleryIHC-P/FFPE:not tested yet |
Immunogen | Synthetic peptide corresponding to AA 28 to 43 from rat GABA-A receptor α1 (UniProt Id: P62813) |
Reactivity | Reacts with: rat (P62813), mouse (P62812).Other species not tested yet. |
Specificity | Specific for GABA-A receptor α1. |
matching control protein/peptide | 224-2P |
Remarks | WB:This protein aggregates after boiling, making it necessary to run SDS-PAGE with non-boiled samples. ICC:This antibody is PFA fixation sensitive, use only mild fixation (2%PFA). Best results are obtained by application on living cells. After washing cells with bound antibodies, they can be fixed and visualized with secondaryreagents. IHC:This antibody requires antigen retrieval with pepsin according to:Lorincz A & Nusser Z (2008).recommended protocol |
