SPECIES REACTIVITY:Human, Mouse
HOMOLOGY:Predicted species reactivity based on immunogen sequence: Rat: (100%), Pig: (100%), Bovine: (100%), Chicken: (85%)
TESTED APPLICATIONS:ELISA, ICC, IF, WB
APPLICATIONS:DAD1 antibody can be used for detection of DAD1 by Western blot at 0.5 to 2 μg/mL. Despite its predicted molecular weight, DAD1 migrates at ~22 kDa in SDS-PAGE. Antibody can also be used for immunocytochemistry starting at 10 μg/mL. For immunofluorescence start at 10 μg/mL.

Antibody validated: Western Blot in human samples; Immunocytochemistry in human samples and Immunofluorescence in human samples. All other applications and species not yet tested.
USER NOTE:Optimal dilutions for each application to be determined by the researcher.
POSITIVE CONTROL:1) Cat. No. 1211 - HepG2 Cell Lysate

Background

BACKGROUND:DAD1 Antibody: Defender of cell death 1 (DAD1) was initially discovered in BHK21 cells as a negative regulator of programmed cell death, a process important for normal organism development and tissue homeostasis. DAD1 was later shown to be a subunit of the mammalian oligosaccharyltransferase complex and is required for its function and structural integrity. Mice lacking DAD1 express abnormal N-linked glycoproteins and undergo increased apoptotic-associated embryonic death. Furthermore, overexpression of DAD1 mRNA is seen in some human hepatocellular carcinomas, indicating it may also play a role in carcinogenesis. It should be noted that DAD1 is not related to the inhibitor of apoptosis proteins (IAP) family and does not contain any baculoviral IAP repeat (BIR) domains.
