SPECIFICITY Endoglin is an endothelial homodimeric membrane antigen containing the tripeptide sequence RGD, which is a recognition motif for adhesion receptors of the integrin family. It has been proposed that endoglin is a TGF-b receptor. Endoglin is a glycoprotein present on endothelial cells of capillaries, arterioles and venules in a variety of tissues and at low levels on acute lymphoblastic and myelocytic leukaemia cells

APPLICATIONS   *Study of monocyte differentiation into macrophages and endoglin up-regulation*Studies in cellular adhesion of circulating blood cells*Lysis of CD105+ cells in the presence of complement*Identification of CD105 positive cells on formalin fixed paraffin wax embedded tissue sections

DATA SHEET: mouse anti-human CD105 clone 266

Catalog#: RDI-CD105-266     $438.00/vial    

Package Size: 100ug purified in 0.2ml (0.5mg/ml) 10mMPBS (pH7.2), 150mM NaCl and 0.09% sodium azide. (sodium azide is toxic,dilute azide compounds with copious amounts of water when disposing in drain to avoid accumulation of explosive deposits-avoid contact with acids.)

Prep: purified from tissue culture supernatant via Protein G affinity chromatography.

Species: mouse IgG1k

CLONE: 266

Workshop Code: not applicable

Activity: Reacts with a homodimeric integral membrane protein comprised of 95Kd subunits (CD105). CD105 is a component of the TGF-B receptor system and can bind TGF-B1 and TGF-B3 with high affinity but does not bind TGF-B2. CD105 is expressed by vascular endothelial cells and syncytiotrophoblasts of placenta and is weakly expressed by stromalfibroblasts. U937 cells and activated macrophages also expresses CD105. Expression of CD105 is increased on activated endothelium in tissues undergoing angiogenesis, ,such as in tumors, or in cases of wound healing or dermal inflammation. This antibody is suitable for formalin fixed parrafin embedded tissue sections without pretreatment (using ABC detection, DAB, positive control tissue human thymus).

Application: -Indirect immunofluorescence cell surface staining

- histochemistry (5-10ug/ml)

Cat#RDI-102PA60  $440.00/200ug vial   Rabbit Anti-human CD105/Endoglin

Description: Produced from sera of rabbits immunised with highly pure recombinant human soluble CD105/Endoglin produced ed in insect cells. The recombinant soluble CD105/Endoglin consists of amino acid 26 (Glu) to 586 (Leu) and is fused to a C-terminal His-tag (6xHis).

Endoglin, also known as CD105, is a Type I integral membrane glycoprotein with a large, disulfide-linked, extracellular region and a short, constitutively phosphorylated, cytoplasmic tail. Two splice variants of human endoglin, the S-endoglin and L-endoglin that differ in the length of their cytoplasmic tails have been identified. Endoglin is highly expressed on vascular endothelial cells, chondrocytes, and syncytiotrophoblasts of term placenta. It is also found on activated monocytes, bone marrow pro-erythroblasts, and leukemic cells of lymphoid and myeloid lineages. Human and mouse endoglin share approximately 70% and 97 % amino acid sequence identity in their extracellular and intracellular domains, respectively.

It has clearly been shown that CD105/Endoglin is required for angiogenesis and it plays a key role in heart development. Mutations in human endoglin or ALK-1 (another type I serine/threonine receptor) lead to the vascular disorder hereditary hemorrhagic telangiectasia (HHT). Mice heterozygous for endoglin have been developed as disease models for HHT. Endoglin has been shown to be a powerful marker of neovascularization. It is also useful as a functional marker that defines long-term repopulating hematopoietic stem cells.

Host species:     Rabbits

Antigen:             Recombinant human soluble CD105/Endoglin

Purification:       Protein-A Chromatography (+his tag depleted)

Stabilizer:         none

Buffer:               lyophilized from PBS, pH 7.4 w/o preservative

Formulation:      lyophilized rabbit IgG

Reconstitution: The lyophilized IgG is stable at 4°C. for at least one month and for greater than a year when kept at -20°C. When reconstituted in sterile water/PBS to a concentration of >0.5 mg/ml the antibody is stable for at least six weeks at 2-4°C. Avoid repeated freeze-thaw cycles. Reconstituted antibody can also be aliquoted and stored at -20°C to -70°C for at least 6 months without detectable loss of activity. Avoid repeated freeze-thaw cycles. -It is recommended that a suitable preservative as 0.09% sodium azide and addition of carrier as 0.1-1% BSA be added to diluted antibody to prevent sticking to sides of vial.


ELISA: Use at 1-15 µg/ml.

Western Analysis: Use at a concentration of 1-2 µg/ml with the appropriate secondary reagents.

Immunohistochemistry: Not investigated so far.

Optimal dilutions should be determined by each laboratory for each application.

Usage: Anti-human CD105/Endoglin is offered for research use. Not for drug use. Not for human use.
