(anti-Human and others as indicated)

RDI Divison of Fitzgerald 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.


Mab to Symplekin

cat#RDI-PRO651100     $375.00/vial  

Clone Determination:     Sym-TJ-E150

Category:                       Mouse monoclonal

Immunoglobulin Class:   IgG1

Purification:                   Hybridoma culture supernatant

Immunogen:                    Human symplekin

Specificity:                   The mab reacts specifically with symplekin ( a 150 kDa polypeptide) present in 1) tight junctions (zonula occludens) of polar epithelia and Sertoli cells of testis (but not their vascular endothelial) and 2) exclusively in the nucleoplasm of these and many other cell types which do not form tight junctions (e.g. stratified epithelia such as oesophagus, tongue mucosa, epidermis, non-epithelia such as fibroblasts, endothelia, lymphocytes).

Polypeptide Reacting: Symplekin, 126.5 kD polypeptide (calculated from a sequence data); apparent M 150 kD (after SDS-PAGE); pl 6.5

Antigen recognized in species (tested so far) Human rat  ; negative with bovine, mouse, Xenopus laevis

Reactivities on Cultured Cell Lines (tested so far): Carcinoma cell lines (e.g. MCF-7, Caco-2, HT29, PLC), SV80 (fibroblasts), U333 CG/343 MG (glioma). K 562(erythroleukemia), RVF (rat vascular smooth muscle cells)

Application: Immunoblotting. Immunohistochemistry: For nucleoplasmic staining a modified Carnoy fixation procedure is suggested (60% ethanol, 30% chloroform, 10% acetic acid) for 20 min, followed by a 10 min ethanol wash

Working Dilution: Ready-to-use for immunohistochemistry

Storage: At 2 - 8'C

Volume: 5ml
