The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
1/500 - 1/1000. Detects a band of approximately 15 kDa (predicted molecular weight: 15 kDa).
1/500 - 1/1000.
Use a concentration of 1 µg/ml. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.
Cytochrome b5 is a membrane bound hemoprotein which function as an electron carrier for several membrane bound oxygenases.
Involvement in disease
Defects in CYB5A are the cause of methemoglobinemia CYB5A-related (METHB-CYB5A) [MIM:250790]. A form of methemoglobinemia, a hematologic disease characterized by the presence of excessive amounts of methemoglobin in blood cells, resulting in decreased oxygen carrying capacity of the blood, cyanosis and hypoxia.
Belongs to the cytochrome b5 family. Contains 1 cytochrome b5 heme-binding domain.
Cytoplasm and Endoplasmic reticulum membrane. Microsome membrane.
IHC image of ab69801 staining in human normal liver formalin fixed paraffin embedded tissue section, performed on a Leica BondTM system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab69801, 1µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.
For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.
