This is a knockout-validated antibody summary, based on the publication "Immunohistological Examination of AKT Isoforms in the Brain: Cell-Type Specificity That May Underlie AKT's Role in Complex Brain Disorders and Neurological Disease", as cited below [1]. Labome curates formal publications to compile a list of antibodies with unambiguous specificity within Validated Antibody Database (VAD).

Figure 1. Western blot analysis of AKT isoform levels in hippocampal lysates prepared from Akt mutant mice. Cre-mediated removal of floxed Akt2 under the early neural progenitor Nes promoter in an Akt3 KO background (n2F3K) led to near-complete removal of both AKT2 and AKT3 in the hippocampus (AKT2: t(5)=12.07, P<0.001; AKT3: t(5)=40.15, P<0.001). This genetic manipulation also led to a significant increase in the AKT1 levels in n2F3K mice when compared with WT controls (t(5)=6.471, P=0.001). Cre-mediated removal of floxed Akt1 under the excitatory neuron Cam2α promoter in an Akt3 KO background (c1F3K) led to a small reduction in AKT1 levels in the hippocampus (t(5)=4.310, P=0.008) with complete AKT3 loss (t(5)=16.99, P<0.001) but no change in AKT2 levels (t(5)=0.340, P>0.05). Nes-Cre-mediated removal of floxed Akt1 and Akt2 (n1F2F) resulted in near-total removal of AKT1 (t(6)=15.45, P<0.001) and AKT2 (t(6)=17.80, P<0.001) but no significant change in AKT3 expression (t(6)=0.297, P>0.05). N=3–4/genotype. From [1].
