Occludin 항체(E-5)는 마우스, 쥐 및 인간 유래의 Occludin 단백질을 WB, IP, IF, IHC(P) 및 ELISA로 검출하는 IgG2b κ 마우스 단일 클론 Occludin 항체(OCLN 항체로도 지정됨)입니다. 옥클루딘 항체(E-5)는 비접합 항-옥클루딘 항체 형태와 아가로스, HRP, PE, FITC 및 다중 Alexa Fluor® 접합체를 포함한 여러 접합 형태의 항-옥클루딘 항체 형태로 제공됩니다. 옥클루딘은 상피세포와 내피세포의 긴밀한 접합부와 밀접하게 관련된 필수 막 단백질입니다. Occludin은 상피와 내피의 타이트 접합(TJ) 구조에 있는 4면체 일체형 막 단백질로 두 개의 세포 외 고리를 포함할 수 있습니다. 이 단백질은 다양한 인산화 형태로 존재합니다. 인산화는 오클루딘의 국소화와 기능을 모두 조절하는 데 관여합니다. 오클루딘의 발현은 고도 불포화 지방산에 의해 상향 조절되어 내피 세포 저항성을 증가시키고 큰 분자에 대한 세포 투과성을 감소시킵니다. 오클루딘의 수준은 조직에 따라 크게 달라지며, 뇌 조직에서는 세포와 세포의 접촉 부위에서 오클루딘이 높게 발현됩니다. 비신경 조직에서는 발현이 낮고 불연속적인 분포를 보입니다. 상피 오클루딘의 상향 조절은 세포막 투과성을 향상시키는 역할을 할 수 있으며, 타이트 접합부의 손상과 관련이 있을 수 있습니다.

연구용으로만 사용가능합니다. 진단이나 치료용으로 사용불가합니다.

Rated 1 out of 5 by from Negative result in pig gut sampleAt necropsy, intestinal tract of pig were dissected. Sample was washed in NaCl 0.9% and post-fixed by immersion for 7 h in 10% buffered formalin (pH 7.4), dehydrated through a graded series of ethanol and finally embedded in Paraplast X-TRA. Four-µm thick sections were cut in the transversal plane and collected on silane-coated slides. After deparaffinization and rehydratation, the Avidin/Biotin blocking was performed and slides were then incubated overnight at room temperature in a dark moist chamber with anti-Occludin (E5) (sc-133256) diluted 1:100 in phosphate buffer saline (PBS). After washing in PBS, sections were incubated for 1.5 hour with Goat Anti-Mouse IgG Antibody (H+L), Biotinylated (6 μg/ml, Vector Laboratories Inc., Burlingame, CA, USA) in a dark moist chamber. The sections were washed twice in PBS and treated with Fluorescein–Avidin D (Vector Laboratories Inc., Burlingame, CA, USA). Finally, the slide with tissue sections was embedded in Vectashield Mounting Medium with DAPI (H-1200, Vector Laboratories Inc., Burlingame, CA, USA) and observed using a Confocal Laser Scanning Microscope (FluoView FV300, Olympus, Tokyo, Japan). Our results did not demonstrate any Occludine-immunopositivity in the epithelial cells of the pig gut mucosa, as expected.

Rated 1 out of 5 by from Negative result in chickens intestinal sampleI tested this anti-occludin antibody on chicken ileum sample by immunohistochemistry. Antigen retrieval was performed using EDTA buffer (pH 9). Antibody was diluted 1:125 in 1,5% horse serum PBS and incubated 2h at RT. Antibody signal was detected using the avidin-biotin-proxidase method. However, it didn't work and no signal was shown.
