Recommended Assay Procedures: Recommended Assay Procedures Clone SXM30 has been shown to be useful for immunoprecipitation (1-2 µg/1x10^6 cells), western blot analysis (1-2 µg/ml), indirect immunofluorescence microscopy of tissuecultured cells, immunohistochemistry of frozen, acetone-fixed tissue sections (1-5 µg/ml), and paraffin-embedded tissue sections requiring antigen retrieval (20 µg/ml). These applications are similar to that described for a related p21 clone, SX118.3.  MCF-7 human breast carcinoma cells (ATCC HTB-22), HL-60 human leukemia cells (ATCC CCL-240), and EL4 mouse lymphoma cells (ATCC TIB-39) are suggested as positive controls. In immunohistochemistry, SX118 staining is primarily nuclear. Tonsil and colon are suggested as positive controls for tissue staining.  In order to obtainn optimal indirect immunohistochemical staining, clone SXM30 should be titrated at 10-20 ug/ml and visualized via a three-step staining procedure in combination with a biotinylated polyclonal anti-mouse Ig (Cat. No. 550337, multiple absorbson) as the secondary antibody and Streptavidin-HRP (Cat. No. 550946) together with the DAB chromogen detection system (Cat. No. 550880). Refer to Fredersdorf et al ., for information regarding induction of p21 expression, and for p21 distribution in different types of human tissues.
Product Notices: Product Notices Since applications vary, each investigator should titrate the reagent to obtain optimal results. 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.
