Preparation And Storage
Store undiluted at 4°C. The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography.
Recommended Assay Procedures
Clone 9.2.27 specifically reacts with a chondroitin sulfate proteoglycan. By immunoprecipitation, it recognizes the fully processed 250 kDa core glycoprotein and a set of precursor polypeptides (210 kDa, 220 kDa, and 240 kDa).
Applications include immunoprecipitation (1 µg/1x10^6 cells), flow cytometry (1-2 µg/ 1x10^6 cells) and immunoflourescence microscopy of cultured cells.
Product Notices
- Since applications vary, each investigator should titrate the reagent to obtain optimal results.
- Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
- Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
- Sodium azide is a reversible inhibitor of oxidative metabolism; therefore, antibody preparations containing this preservative agent must not be used in cell cultures nor injected into animals. Sodium azide may be removed by washing stained cells or plate-bound antibody or dialyzing soluble antibody in sodium azide-free buffer. Since endotoxin may also affect the results of functional studies, we recommend the NA/LE (No Azide/Low Endotoxin) antibody format, if available, for in vitro and in vivo use.
- An isotype control should be used at the same concentration as the antibody of interest.
- For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.

Antibody Details
9.2.27
The 9.2.27 monoclonal antibody specifically binds to CSPG4 (chondroitin sulfate proteoglycan 4). CSPG4 is also known as MCSP (melanoma chondroitin sulfate proteoglycan) and NG2 (neural/glial antigen 2). The hybridoma secreting the 9.2.27 antibody was generated using a human melanoma cell extract as the immunogen. Tumor cells display a variety of antigens which have been defined by antibodies. Antibodies that specifically react with tumor-associated antigens are useful in understanding the biology of particular tumor types. Proteoglycans including chondroitin sulfate, keratan sulfate, dermatan sulfate and heparan sulfate are major components of the extracellular matrices of many animal cell types. Clone 9.2.27 has been shown to react with human melanoma cells, glioma cells, and proliferating brain endothelial cells. It did not react with fetal melanocytes, neuroblastoma LA-N-1 cells or a variety of carcinoma, lymphoid, and fibroblastoid cell lines. Additionally, neither white nor gray matter from the medulla oblongata, cerebellum or spinal cord of a normal human adult reacted with 9.2.27. Clone 9.2.27 has also been used in functional studies to investigate the role of chondroitin sulfate proteoglycans in human tumor cell systems. It has been shown to block melanoma cell spreading, exhibit antiproliferative effects on glioma cells in vitro and suppress glioma tumor growth in athymic nude mice models.
A soluble extract derived from M14 human melanoma cells bound to lens culinaris lectin-Sepharose and depleted of fibronectin was used as immunogen.

Format Details
Purified
Tissue culture supernatant is purified by either protein A/G or affinity purification methods. Both methods yield antibody in solution that is free of most other soluble proteins, lipids, etc. This format provides pure antibody that is suitable for a number of downstream applications including: secondary labeling for flow cytometry or microscopy, ELISA, Western blot, etc.
