(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.

ANTI-Actin  (see monolconals and polyclonals below)

-seee also cardiac actin and pure actin antigen

Mouse anti-Actin (skeletal mucle)

-cat#RDI-ACTINSKabm   $375.00/100ug   - cat#RDI-ACTINSKabm-1 $500.00/200ug

-clone ref: 5C5.F8.C7, mIgM isotype

-reacts with the alpha-skeletal and alpha cardiac (sarcomeric) actins. Shows no cross-reaction with smooth muscle actin. The antibody reacts with sarcomeric actins of normal tissues and neoplasms derived from such tissues (as rhadomyosarcomas).

-species reactivity includes: human, bovine, rabbit, sheep, rat, guinea pig, frog, snake and carp (others nto tested).

-uses: histochemistry (forzen and formalin fixed/paraffin embedded sections) , immunofluorescence and Elisa (for Elisa order without BSA, use cat#RDI-ACTINSKabmX)

-staining pattern: cytoplasmic using skeletal or cardiac muscle as positve control.

-Note: Recommend using a specific anti-IgM secondary antibody.

Bulk quotes on request

Positive  Cntrl: smooth muscle or leimyosarcoma

Localization: Cytoplasmic

Background: Recognizes the alpha-smooth muscle isoform of actin. It shows no cross reaction with actin from fibroblasts (Beta and gamma cytoplasmic), striated muscle (alpha sarcomeric), and myocardium. It epitope is composed of the acetyl group and the first 4 amino acids on the N-terminal end of the peptidic chain of alpha smooth muscle.

Storage: 2-8 deg c

Immunogen: chicken gizzard actin

Isotype: mIgG1k

Clone: ACTN05

Hybridoma: Produced by the fusion between CB6F1/J splenocytes and mouse myeloma SP2/O cells.

Reactivity: human,cow, mouse, dog, rabbit, rat, chicken, Dictyostelium discoideum, Physarum polycephalum, others not tested

Uses: -Western blot: 0.5ug/ml for 2 hours rt


          Optimal titter must be dtermined ofr each use.

Positive  Cntrl: HeLa, Rh30 or LS174T cells or muscle or sarcoma.

Localization: Cytoplasmic

Background: Reacts with all six known vertebrate isoactins as well as Dictyostelium discoideum and physarum polycephalum actins. It also reacts with twocytoplasmic actins (beta, gamma) which are highly homologous to one another but which differ from the muscle actins at about 25 amino acid residues.
