Citric Acid 68-75 MIB E3 ubiquitin protein ligase 1 Homo sapiens 152-157 8514278-2 1993 One such antibody, MIB1, recognizes a fixation and embedding resistant epitope on the Ki-67 protein if sections are previously microwaved in a citrate buffer. Citric Acid 143-150 MIB E3 ubiquitin protein ligase 1 Homo sapiens 19-23 10937051-8 2000 Boric acid was used for antigen retrieval on sections stored for 12 weeks at 20 degrees C. For both p53 protein and MIB1 antigen, this resulted in an extent and intensity of immunostaining equal to or higher than (MIB1) that obtained in freshly cut sections, using citrate buffer. Citric Acid 265-272 MIB E3 ubiquitin protein ligase 1 Homo sapiens 116-120
