Product nameAnti-SLUG antibody
See all SLUG primary antibodies
DescriptionRabbit polyclonal to SLUG
Specificityab27568 detects the overexpressing human Slug protein, however we have no data on the detection of the endogenous Human protein with this current batch. ab27568 does not cross react with overexpressed SNAIL protein in cell lysates.
Tested applicationsSuitable for: WB, IHC-Fr, ICC/IFmore details
Species reactivityReacts with: Mouse, Rat, Chicken
Predicted to work with: Cow, Dog, Human, Pig, Xenopus laevis
- This antibody gave a positive signal in the following tissue lysates: Mouse heart, Rat heart as well as MCF7 cell lysate overexpressing SLUG protein.

FunctionTranscriptional repressor. Involved in the generation and migration of neural crest cells.
Tissue specificityExpressed in placenta and adult heart, pancreas, liver, kidney and skeletal muscle.
Involvement in diseaseDefects in SNAI2 are the cause of Waardenburg syndrome type 2D (WS2D) [MIM:608890]. WS2 is a genetically heterogeneous, autosomal dominant disorder characterized by sensorineural deafness, pigmentary disturbances, and absence of dystopia canthorum. The frequency of deafness is higher in WS2 than in WS1.
Sequence similaritiesBelongs to the snail C2H2-type zinc-finger protein family.
Contains 5 C2H2-type zinc fingers.

Observed band size: 34 kDa why is the actual band size different from the predicted?
ab27568 detects a band of 34 kDa in MCF7 cells that have been transfected with a vector that overexpresses the SLUG protein. This antibody does not crossreact with the SNAIL protein, as it did not recognize this protein in MCF7 cells overexpressing SNAIL. ab27568 was unable to detect endogenous SLUG in MDA-MB231 cells (not shown).
ab27568 staining mouse embryonic stem cells by ICC/IF. Cells were formaldehyde fixed and permeabilized in 0.1% Triton X-100 prior to blocking with 0.1% BSA and 1% serum for 30 minutes at 21°C. The primary antibody was diluted 1/100 and incubated for 2 hours at 21°C. An Alexa Fluor® 488 conjugated goat anti-rabbit antibody, diluted 1/500, was used as the secondary.
