For western blots, incubate membrane with diluted primary antibody in 5% w/v nonfat dry milk, 1X TBS, 0.1% Tween® 20 at 4°C with gentle shaking, overnight.
NOTE: Please refer to primary antibody product webpage for recommended antibody dilution.
NOTE: Prepare solutions with reverse osmosis deionized (RODI) or equivalent grade water.
Load 20 µl onto SDS-PAGE gel (10 cm x 10 cm).
NOTE: Loading of prestained molecular weight markers (#59329, 10 µl/lane) to verify electrotransfer and biotinylated protein ladder (#7727, 10 µl/lane) to determine molecular weights are recommended.
NOTE: Volumes are for 10 cm x 10 cm (100 cm2) of membrane; for different sized membranes, adjust volumes accordingly.
* Avoid repeated exposure to skin.

Human, Monkey
Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Pro199 of human CD46 protein.
Complement Regulatory Protein; Membrane Cofactor Protein (CD46) is a type 1 membrane protein that plays an important inhibitory role in the complement system (1). CD46 exhibits a cofactor activity that promotes inactivation of C3b and C4b by serum factor 1, thereby protecting host (self) cells from complement-dependent cytotoxicity (1,2). The importance of CD46 to complement regulation is underscored by the observation that genetic loss of CD46 leads to development of atypical hemolytic-uremic syndrome (aHUS), a disease characterized by uncontrolled complement activation (2,3). In addition to its role in complement inactivation, CD46 can function as a receptor for selected bacteria and viruses (4), and is reportedly required for proper fusion of spermatozoa to the oocyte membrane during fertilization (5). CD46 is implicated in the development and/or progression of selected cancer types. For example, research studies show elevated CD46 expression in medulloblastoma tumor samples (6), while CD46 expression has been linked with poor prognosis in breast cancer (7). It has been suggested that upregulation of CD46 may serve to protect cancer cells from complement-dependent cytotoxicity, thereby evading destruction by the immune system (8,9).
