Our Abpromise guarantee covers the use of ab28244 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|ICC/IF||Use a concentration of 1 - 10 µg/ml.|
|IHC-P||Use at an assay dependent concentration. PubMed: 18403594|
|Flow Cyt||1/50. PubMed: 20361950
ab171870 - Rabbit polyclonal IgG, is suitable for use as an isotype control with this antibody.
|WB||1/1000 - 1/5000. Detects a band of approximately 110-120 kDa (predicted molecular weight: 88 kDa). 1/1000 when using colorimetric substrates such as BCIP/NBT - 1/5000 when using chemiluminescent substrates. Note: EDTA/EGTA treatment of tissues or lysates is required to see latent zymogen. Dilution optimised using Chromogenic detection.|
FunctionIn association with DPP4 is involved in the pericellular proteolysis of the extracellular matrix (ECM), the migration and invasion of endothelial cells into the ECM. May have a role in tissue remodeling during development and wound healing, and may contribute to invasiveness in malignant cancers.
Tissue specificityFibroblast specific.
Sequence similaritiesBelongs to the peptidase S9B family.
The N-terminus may be blocked.
Cellular localizationCell membrane. Cell projection > lamellipodium membrane. Cell projection > invadopodium membrane. Found in cell surface lamellipodia, invadopodia and on shed vesicles. Colocalized with DPP4 in invadopodia and lamellipodia of migratory activated endothelial cells in collagenous matrix. Colocalized with DPP4 on endothelial cells of capillary-like microvessels but not large vessels within invasive breast ductal carcinoma.

ICC/IF image of ab28244 stained MEF1 cells. The cells were 4% PFA fixed (10 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 (ab28244, 1µg/ml) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit 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.
