Price: 150 € / 5 ml

Monoclonal Antibodies

Origin:	Mouse

Isotype:	IgG1

Clone:	SPM471

Format:	ready to use

Quantity:	5 ml

Working concentration:	neat

Presentation:	Antibody solution in stabilizing phosphate buffer pH 7.3. Contains 0.09 % sodium azide**. The volume is sufficient for at least 50 immunohistochemical tests (100 µl working solution / test). Use appropriate antibody diluent e.g. BIOLOGO Art. No. PU002, if further dilution is required.

Immunogen:	Human Uvomorulin (E-Cadherin)

Specificity:	E-Cadherin 120 kDa Epitop aa 600-707

Species Specificity:	Human

General Information:	E-Cadherin (Uvomorulin, ARC-1) is a Ca2+-dependent trans-membrane protein, which plays an important role for the cell connection in epithelia. Ligands for E-Cadherin are catenins, which bind to actin filaments of the cyto-skeleton. The cell to cell adhesion during embryo genesis is dependent of the interrelation of these three components. Reduced expression of E-Cadherin in carcinoma has been discussed as a factor influencing tumour invasion and bad prognosis of cancer.

Special properties:	The antibody to E-cadherin is well suited to detect this glycoprotein in different types of epithelia. The localization is limited to the lateral cell membrane.

Positive control:	Small intestine, appendix, corneal epithelium

Pre-treatment:	Pre-treatment with Unmasking Fluid H (Art. No. DE008) at 96-100° C improves the staining results remarkably. For cryostat material acetone fixation (ice cold!) is recommended.

Applications:	C, P

Incubation time:	60 min at RT

Secondary reagents:	We recommend the use of BIOLOGO's Universal Staining System DAB (Art. No. DA005) or AEC (Art.-No. AE005), if higher sensitivity is required VECTASTAIN Elite ABC (Art. No. PK-6102) or ABC AP (Art. No. AK-5002) systems are applicable.

Storage:	2-8°C
