OTX2 Antibody in Western Blot (WB) — Western blot was performed using Anti-OTX2 Monoclonal Antibody (1H12C4B5) (Product # MA5-15854) and a 32 kDa band corresponding to OTX2 was observed in mouse retina and rat retina as compared to other tissues. A band at ~25kDa corresponding to circulating tissue IgG was observed in the Mouse tissue lysates. Tissue extracts (30 µg lysate) of Mouse retina (Lane 1), Mouse lung (Lane 2), Mouse eye (Lane 3) Mouse brain (Lane 4) and Rat retina (Lane 5) were electrophoresed using Novex® NuPAGE® 12 % Bis-Tris gel (Product # NP0342BOX). Resolved proteins were then transferred onto a nitrocellulose membrane (Product # IB23001) by iBlot® 2 Dry Blotting System (Product # IB21001). The blot was probed with the primary antibody (1:1000 dilution) and detected by chemiluminescence with Goat anti-Mouse IgG (H+L) Superclonal™ Recombinant Secondary Antibody, HRP (Product # A28177, 1:4000 dilution)using the iBright FL 1000 (Product # A32752). Chemiluminescent detection was performed using Novex® ECL Chemiluminescent Substrate Reagent Kit (Product # WP20005).

OTX2 Antibody in Immunohistochemistry (IHC) — Immunofluorescent analysis of cerebral organoids (A) 26 days in vitro (DIV) COs have ventricular and subventricular zones immunopositive for differentiated neurons (TUJ1 + cells), neural stem cells (SOX2 + cells; green), immature neurons (NeuroD1 + cells; red), proliferative (Ki67 + cells; green), and apoptotic (cleaved caspase 3 + cells; red) cells. An elevated number of cleaved caspase-3+ cells may indicate increased neurosis in larger hCOs. (B) 45DIV COs comprise EAAT1 + and GFAP + astrocytes, as well as late immature neuron markers [NeuN (green) and MAP2 (red)]. (C) COs generated following this protocol are immunopositive for forebrain marker PAX6 and forebrain/midbrain marker OTX2, but not midbrain marker EN1 or hindbrain (GBX2) markers. All scale bars are 100 mum.

OTX2 Antibody in Immunohistochemistry (IHC) — Fig. 10 High activation of the canonical Wnt pathway in hESC-derived organoids causes suppression of ChPe markers. a A schematic presentation of the protocol for the treatment of organoids with the canonical Wnt agonist CHIR. b , c The ChP marker TTR is present in the periphery of a day 25 organoid exposed to 3 muM, but not when exposed to 12 muM CHIR, from day 18. c N = 4 organoids (3 muM CHIR) and 5 organoids (12 muM CHIR treated); were used for immunohistochemistry analysis. d High magnification images (boxed region shown in b) of serial sections of a day 40 organoid exposed to 3 muM reveal the presence of TTR, AQP1, and OTX2 in the periphery. This labeling is reduced or undetectable upon exposure to higher concentrations of CHIR (6/9/12 muM). d N = 14 organoids (3 muM CHIR), 9 organoids (6 muM CHIR), 5 organoids (9 muM CHIR treated), and 14 organoids (12 muM CHIR treated) from 2 independent experiments were used for analysis (each organoid was considered as an independent biological replicate). Additional examples are provided in Supplementary Fig. S10 . e q-PCR analysis shows that the expression of the ChP markers TTR, AQP1 , and OTX2 is upregulated in organoids at day 30 organoids exposed to 3 muM CHIR from day 18. This increased expression is lost upon treatment with 12 muM CHIR for the same period. ( f ) LEF1 expression displays a stepwise increase upon 3 muM and 12 muM CHIR treatment, consistent with increased activation of the canonical Wnt pathway. Bar graphs ( e ,

OTX2 Antibody in Immunohistochemistry (IHC) — Fig. 6 Morphological, immunohistochemical, and molecular features of Rax - creER T2 ::Ctnnb1(ex3) fl/+ SmoM2 fl/+ ( RBS ) ocular lesions match with IO-MEPL as opposed to retinoblastoma. a Morphology of murine RBS lesion after tamoxifen administration on day E8.5 (left column) compared to IO-MEPL (middle column) and human retinoblastoma (right column). Flexner-Wintersteiner-Rosettes in retinoblastoma were smaller in comparison to the pseudostratified rosettes of IO-MEPL and RBS (first row). IO-MEPL and RBS stained strongly for MAP2C, while rosette structures consistently lacked staining signal. In contrast, retinoblastoma displayed strong MAP2C positivity with most prominent staining intensity towards the luminal surfaces of rosettes (second row). SOX2-positive cells were found in IO-MEPL and RBS in a scattered distribution with occasional accentuation of staining intensity in association with rosettes or rosette-like structures, while SOX2 staining was negative in Retinoblastoma (third row). OTX2-positive cells were occasionally found in IO-MEPL in association with rosettes or rosette-like structures and in RBS in the residual retina and NBL-like rosettes. In contrast, retinoblastoma stained negative for OTX2 (fourth row). Scale bar is 100 um. b Hierarchical clustering based on cross-species harmonized gene expression data of this study, GSE30074 [] and GSE172170 []. Ocular lesions of RBS mice formed a distinct cluster with closest similarity to human IO-MEPLs, but not human

OTX2 Antibody — Antibody specificity was demonstrated by detection of differential basal expression of the target across tissue tested owing to their inherent genetic constitution. Relative expression of OTX2 was observed in Mouse retina in comparison to Mouse Brain, Mouse Eye and Mouse Lung using Anti-OOTX2 Monoclonal Antibody (1H12C4B5) (Product # MA5-15854) in Western Blot. {RE}

产品详细信息

MA5-15854 targets OTX2 in indirect ELISA, FACS, IF, IHC, and WB applications and shows reactivity with Human samples.

The MA5-15854 immunogen is purified recombinant fragment of human OTX2 expressed in E. Coli. .

MA5-15854 detects OTX2 which has a predicted molecular weight of approximately 32kDa.

靶标信息

OTX2 is a 289 amino acid containing protein encoding a member of the bicoid sub-family of homeodomain-containing transcription factors. It has two known alternative splice variants with distinct isoforms though presence of other isoforms cannot be excluded. The protein is an early marker of endodermal differentiation of embryonic stem cells and may play a role in the development of the brain and the sensory organs. The protein may bind to BCD target sequence (BTS): 5-'TCTAATCCC-3'. Defects in OTX2 are the cause of microphthalmia syndromic type 5 (MCOPS5).
