関連疾患
Defects in OTX2 are the cause of microphthalmia syndromic type 5 (MCOPS5) [MIM:610125]. Microphthalmia is a clinically heterogeneous disorder of eye formation, ranging from small size of a single eye to complete bilateral absence of ocular tissues. Up to 80% of cases of microphthalia occur in association with syndromes that include non-ocular abnormalities. MCOPS5 patients manifest unilateral or bilateral microphthalmia/clinical anophthalmia and variable additional features including coloboma, microcornea, cataract, retinal dystrophy, hypoplasia or agenesis of the optic nerve, agenesis of the corpus callosum, developmental delay, joint laxity, hypotonia, and seizures. -

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-Otx2 antibody (ab114138)
IHC image of Otx2 staining in a section of formalin-fixed paraffin-embedded normal mouse e14 foetal brain performed on a Leica BOND™ system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20mins. The section was then incubated with ab114138, 2.5ug/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX. The inset secondary-only control image is taken from an identical assay without primary antibody.
For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.

The image on the left is of a WT embryo, whilst on the right is an embryo where Otx2 has been replaced with human Otx1 (hOtx1Otx2/Otx2). The sections underwent heat mediated antigen retrieval using Citrate Buffer, primary antibody was used at 1:500 dilution and Biocare Mach4 Kit was used to detect the primary antibody.

The sections were deparffinized and subjected to heat mediated antigen retrieval using citric acid. The section were then blocked using 1% BSA for 10 mins at 21°C. ab114138 was diluted 1:1500 using TBS/BSA/Azide and incubated for 2 hours at 21°C. The secondary antibody used was goat polyclonal to rabbit IgG conjugated to Biotin (1:250).

Lysates/proteins at 0.1 µg per lane.
Secondary
All lanes : Goat Anti-Rabbit IgG H&L (HRP) (ab97051) at 1/10000 dilution
Developed using the ECL technique.
Performed under reducing conditions.
Predicted band size: 32 kDa
Observed band size: 37 kDa why is the actual band size different from the predicted?
Additional bands at: 62 kDa. We are unsure as to the identity of these extra bands.
Exposure time: 8 minutes
Lane 1 represents the Otx1 Recombinat protein which was used as a negative control for ab114138. This blot was produced using a 10% Bis-tris gel under the MOPS buffer system. The gel was run at 200V for 50 minutes before being transferred onto a Nitrocellulose membrane at 30V for 70 minutes. The membrane was then blocked for an hour using 5% Bovine Serum Albumin before being incubated with ab114138 overnight at 4°C. Antibody binding was detected using an anti-rabbit antibody conjugated to HRP, and visualised using ECL development solution. -
