Anti-CSPG4 Antibody

Mouse proteoglycan.

Anti-Chondroitin 4 Sulfate Antibody, clone BE-123 detects level of Chondroitin 4 Sulfate & has been published & validated for use in ELISA, RIA & WB.

ELISA at 1:400-1:3,200.

RIA at 1:50-1:6,400.

Immunohistochemistry: This antibody only reacts with digested material. Fixed tissue must be digested with chondroitinase ABC (Sigma).
The Reference 23757342 should be indicated for IHC. (Reine, TM., et al., PubMed ID: 23757342)

Western Blot: 1:1000-1:4000 using ECL detection method. Chondroitinase ABC treatment of lysate sample is helpful.
In any alkali buffer, e.g. Tris or acetate (50mM or 100mM) pH 7.4-7.6. Make a stock solution by diluting one vial of Sigma Chondroitinase A, B, C, (5 units/vial) in 100 µL . For use, dilute stock 10-fold into the buffer of choice. Use at a ratio of 50-100mg of proteoglycan per 5 units of enzyme. On fixed cells, dilute in Tris acetate and on non-fixed cellsy dilute 10-25 fold in DMEM.

Reacts with both mouse (fetal and adult) and human (fetal and adult) chondroitinase ABC digested cartilage proteoglycans. Chondroitin-4 sulfate disaccharides successfully inhibit the binding of monoclonal antibody to proteoglycans. No reaction with native proteoglycans or with proteoglycans digested with either chondroitinase AC or testicular hyaluronidase.

Ascites fluid containing no preservatives.

Maintain at -20°C in undiluted aliquots for up to 12 months from date of receipt. Avoid repeated freeze/thaw cycles.
