DescriptionRabbit polyclonal to PROX1
SpecificityWe have had mixed results for use of this antibody in IHC-P. The abReview below from an external researcher reports good staining with this antibody with human heart tissue, but we have had mixed results with this antibody in internal QC testing in IHC-P. Thus, we are removing IHC-P as a guaranteed application and welcome any feedback from customers who have used this antibody in IHC-P.
Tested applicationsSuitable for: WB, IHC-Pmore details

Our Abpromise guarantee covers the use of ab38692 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 2 µg/ml. Detects a band of approximately 105 kDa (predicted molecular weight: 83 kDa).|
|IHC-P||Use at an assay dependent concentration.|
FunctionTranscription factor involved in developmental processes such as cell fate determination, gene transcriptional regulation and progenitor cell regulation in a number of organs. Plays a critical role in embryonic development and functions as a key regulatory protein in neurogenesis and the development of the heart, eye lens, liver, pancreas and the lymphatic system. Involved in the regulation of the circadian rhythm. Represses: transcription of the retinoid-related orphan receptor RORG, transcriptional activator activity of RORA and RORG and the expression of RORA/G-target genes including core clock components: ARNTL/BMAL1, NPAS2 and CRY1 and metabolic genes: AVPR1A and ELOVL3.
Tissue specificityMost actively expressed in the developing lens. Detected also in embryonic brain, lung, liver and kidney. In adult, it is more abundant in heart and liver than in brain, skeletal muscle, kidney and pancreas.
Sequence similaritiesBelongs to the Prospero homeobox family.
Contains 1 Prospero-type homeobox DNA-binding domain.
DomainThe prospero-type homeobox DNA-binding domain is essential for repression of RORG transcriptional activator activity.
Cellular localizationNucleus. RORG promotes its nuclear localization.
- Information by UniProt
FormProx1 is a specific and required regulator of the development of the lymphatic system and that the vascular and lymphatic systems develop independently. Sox18 directly activates Prox1 transcription by binding to its proximal promoter.

Performed under reducing conditions.
Predicted band size: 83 kDa
Observed band size: 95 kDa why is the actual band size different from the predicted?
Additional bands at: 25 kDa. We are unsure as to the identity of these extra bands.
Exposure time: 4 minutes
Formaldehyde-fixed, paraffin-embedded human heart tissue stained for PROX1 using ab38692 at 1/250 dilution in immunohistochemical analysis. Incubation with primary antibody was performed for 45 minutes at 20°C. Goat anti-rabbit/mouse HRO polymer was used as a secondary antibody.
Heat mediated antigen retrieval was performed. Tissue sections were blocked with peroxidase for 5 minutes followed by a 10 minute protein block.
