General Western Blot Protocol (KPL) This procedure was written as a general protocol for use with standard Tris-Glycine SDS-PAGE gels and nitrocellulose membranes. It should give acceptable results in most situations. Optimization for particular situations may require modifying the conditions described.

·ECM Protocols Western Blot(LTI) General protocol for ECM assay. A mixture of protein is separated electrophoretically by SDS-PAGE, and the individual protein bands are transferred to nitrocellulose paper. Specific antibody is then used to probe for any of the bands it might bind to, and the nonbound antibody is washed away. The bound antibody is then detected by the addition of a second antibody against the immunoglobulin species contained in the first antibody. This second antibody is labeled with an enzyme, and the specific protein band can then be visualized by the addition of an enzyme substrate containing a color developer.

·Enzyme-Assisted Immunoelectroblotitng (IEB or Western Blotting) (Molecular Biology Techniques Manual) This protocol describes the use of horizontal blotting of simple SDS-PA gels, and subsequent detection of proteins using rabbit antisera and alkaline phosphatase-conjugated goat-anti-rabbit IgG, detected using bromo-chloro-indolyl phosphate (BCIP) and Nitro-blue tetrazolium (NBT) salts.
·Protein Dot-/Slot-Blotting (Schleicher & Schuell) Dot-blots of protein simplify quantitative assays by direct application of the sample to a membrane or filter sheet without prior fractionation. The technique is used for carrying out binding assays on multiple samples, and is valuable for studies in which purification or other processing of the molecule may alter biological activity. The latter advantage makes the dot-blot technique ideal for preliminary screening to determine the effect of blotting or assay conditions on the activity of the sample.
·Too Many Bands on Western Blot (Synaptic Systems) It is not uncommon that, contrary to the theoretical predictions, several bands are detected. Although it is possible that the antibody is not entirely specific for the protein, other factors may be responsible
