(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, histochemistry, 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.

Monoclonal anti-desmin

cat#RDI-PRO10519   $375.00./vial

clone: D9

Antigen: isolated from human leiomyoma

presentation: 1ml tissue culture supernatant

Reactivity:  human, most mammals including mouse, rat and rabbits

Application: Clone D9 specifically reacts with the cytoplasmic 53Kda desmin protein. Desmin is the main intermediate filament in mature skeletal, cardiac and smooth mucle cells. the antibody can be used to distinguish rhabdomyosarcomas and leiomyosarcomas from ohter soft tissue tumors, lymphomas and carcinomas. Clone D9 does not cross react with other intermediate filament proteins and is useful for the identification of myodifferentiation in tumors.

Positive control:skeletal and smooth muscle myosarcomas

USE: histochemistry, paraffin sections (proteolytic treatment with pronase or trypsin required), western blot

Dilution: 1:10 histochemistry (optimize for each method)

dilution buffer: PBS with 1% BSA and 0.01% Na-Azide

Storage: 4 DEG C (undiluted)

Pab to Desmin

cat#RDI-PRO10570   $344.00/vial  

Category Rabbit polyclonal

Form/Purification Rabbit serum

Ig Class IgG

Immunogen Chicken gizzard

Clinical Application/Specificity: Desmin is the main intermediate filament in mature skeletal, cardiac and smooth-muscle cells. The antibody can be used to distinguish rhabdomyo-sarcomas and leiomyosarcomas from other soft tissue tumors, lymphomas and carcinomas. It reacts with the 53 kDa desmin protein and does not crossreact with other intermediate filament proteins.

Recommended Positive Control: Skeletal and smooth muscle myosarcomas
