Our Abpromise guarantee covers the use of ab105217 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|WB||Use a concentration of 1 µg/ml. Detects a band of approximately 120 kDa (predicted molecular weight: 103 kDa).|
|ICC/IF||Use a concentration of 1 µg/ml.|
FunctionIsoform 1: Cleaves GlcNAc but not GalNAc from O-glycosylated proteins. Can use p-nitrophenyl-beta-GlcNAc and 4-methylumbelliferone-GlcNAc as substrates but not p-nitrophenyl-beta-GalNAc or p-nitrophenyl-alpha-GlcNAc (in vitro) (PubMed:11148210). Does not bind acetyl-CoA and does not have histone acetyltransferase activity (PubMed:24088714).
Isoform 3: Cleaves GlcNAc but not GalNAc from O-glycosylated proteins. Can use p-nitrophenyl-beta-GlcNAc as substrate but not p-nitrophenyl-beta-GalNAc or p-nitrophenyl-alpha-GlcNAc (in vitro), but has about six times lower specific activity than isoform 1.
Tissue specificityUbiquitous. Shows highest expression in the brain, placenta and pancreas.
Sequence similaritiesBelongs to the glycosyl hydrolase 84 family.
modificationsProteolytically cleaved by caspase-3 during apoptosis. The fragments interact with each other; cleavage does not decrease enzyme activity.
Cellular localizationCytoplasm and Nucleus.

Lanes 1 - 4: Merged signal (red and green). Green - ab105217 observed at 120 kDa. Red - loading control, ab8245, observed at 37 kDa.
ab105217 was shown to recognize in wild-type HAP1 cells as signal was lost at the expected MW in MGEA5 knockout cells. Additional cross-reactive bands were observed in the wild-type and knockout cells. Wild-type and MGEA5 knockout samples were subjected to SDS-PAGE. The membrane was blocked with 3% NF Milk. Ab105217 and ab8245 (Mouse anti-GAPDH loading control) were incubated overnight at 4°C at 1 ug/ml and 1/20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preabsorbed ab216773 and Goat anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed ab216776 secondary antibodies at 1/20000 dilution for 1 hour at room temperature before imaging.
ab105217 stained SKNSH cells. The cells were 100% methanol fixed (5 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody ab105217 at 1µg/ml overnight at +4°C. The secondary antibody (green) was DyLight® 488 goat anti- rabbit (ab96899) IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.
