Product Usage Information

Application Dilution
Western Blotting 1:1000
Immunoprecipitation 1:200

Storage

Supplied in 10 mM sodium HEPES (pH 7.5), 150 mM NaCl, 100 µg/ml BSA and 50% glycerol. Store at –20°C. Do not aliquot the antibody.

Specificity / Sensitivity

MB21D2 Antibody recognizes endogenous levels of total MB21D2 protein. This antibody detects a 180 kDa band of unknown origin.

Species Reactivity:

Human

Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues near the carboxy terminus of human MB21D2 protein. Antibodies are purified by protein A and peptide affinity chromatography.

Background

MB21D2 (Mab-21 domain-containing protein 2, C3orf59) belongs to a protein family of cGAS/DncV-like nucleotidyltransferase (CD-NTase) enzymes involved in a variety of cellular processes, including cell survival, proliferation, and migration (3). MB21D2 is an intracellular E-cadherin binder which carries a recurrent Q311E mutation (1,4). Both wild type and Q311E mutant MB21D2 have been identified as being frequently overexpressed in lung, head, and neck cancers, and may mediate pro-oncogenic activities by promoting EMT/cancer stemness (2-4).

Species Reactivity

Species reactivity is determined by testing in at least one approved application (e.g., western blot).

Western Blot Buffer

IMPORTANT: 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.

MB21D2 Antibody

Western Blotting Image 1: MB21D2 Antibody Expand Image
Western blot analysis of extracts from various cell lines using MB21D2 Antibody (upper) or β-Actin (D6A8) Rabbit mAb #8457 (lower).
Western Blotting Image 2: MB21D2 Antibody Expand Image
Western blot analysis of extracts from HEY A8 wild-type (WT) and knockout (KO) cells using MB21D2 Antibody (upper) and β-Actin (D6A8) Rabbit mAb #8457 (lower). As expected, the HEY A8 KO cells do not show expression of MB21D2.
Immunoprecipitation Image 1: MB21D2 Antibody Expand Image
Immunoprecipitation of MB21D2 protein from HDLM-2 extracts. Lane 1 is 10% input, lane 2 is Normal Rabbit IgG #2729, and lane 3 is MB21D2 Antibody. Western blot analysis was performed using MB21D2 Antibody. Mouse Anti-Rabbit IgG (Light-Chain Specific) (D4W3E) mAb (HRP Conjugate) #93702 was used as the secondary antibody.
