  ANTIBODIES  

(anti-Human and others as indicated)

RDI Divison of researchd Industries Intl  offers a wide line of  antibodies. Since no one antibody works best for all applications (neutralization, blotting, ELISA, etc), we offer many different types of antibodies to help solve this problem. Please inquire for other applications or types of antibodies not listed below.

cat# RDI-GFAPabrX    $406.00/0.5ml

        RDI-GFAPabrX1  $625.00/1ml

Presentation: purified antibody in 10mM PBS with 0.2% BSA and 0.09% NaN3.

Immunogen: purified GFAP from cow spinal cord

Reactivity: human, mouse, rat, monkey, bovine, sheep, guinea pig, chicken and hamster. Others not tested.

Uses: -histochemistry (formalin/paraffin sections)   -approx ab concentration 1:200, 30min RT

Positive Ctrl: brain or astrocytoma

Localization: Cytoplasmic

Background: stains astrocytes, glial cells, ependymal cells and their corresponding tumors. In the peripheral nervous system, Schwann cells, satellite cells, and enteric glial cells are stained. Weak stainging of axons has been observed. Absorption studies show that this is caused by a cross-reaction with neurofilament protein.

Storage: 2-8 deg c
