Specifications

Clone Host Grade Applications
Polyclonal Guinea pig Serum B IH
Plectin, a 500kD intermediate filament binding protein, is localized to the cytoplasm and acts to both stabilize and give strength to cells via cross-linking (1). Plectin cross-links intermediate filaments to microtubules and microfilaments, and anchors intermediate filaments to the plasma and nuclear membranes (2,3). Plectin binds many proteins, including actin, vimentin, and Lamin B. Phosphorylation by PKA or PKC results in decreased binding to Lamin B, and phosphorylation by PKA enhances the plectin-vimentin interactions (4).
Catalog #P4214-31
Plasma membrane attachment sites of intermediate filaments and microfilaments (actin) such as desmosomes and hemidesmosomes, Z-line structures and dense plaques of striated and smooth muscle. Strong positive reaction is also found with endothelia, fibroblasts and infiltrating cells (e.g. lymphocytes).
ApplicationsSuitable for use in Western Blot and Immunohistochemistry. Optimal dilutions to be determined by the researcher.
Recommended DilutionWestern Blot: 1:16,000 (ECL)
Immunohistochemistry (frozen and paraffin sections, enhanced after microwave treatment): 1:500: Incubate for 1 hr at RT; extended with paraffin sections.
Optimal dilutions to be determined by the researcher.
Storage and StabilityMay be stored at 4°C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Aliquots are stable for at least 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.

ImmunogenC-terminal C domain of human recombinant plectin (aa 4367 - 4684).
SpecificityRecognizes human protein plectin at 53kD localizing to plasma membrane attachment sites of intermediate filaments and microfilaments (actin) such as desmosomes and hemi- desmosomes, Z-line structures and dense plaques of striated and smooth muscle. Specifically recognizes human glia cells. Strong positive reaction is also found with endothelia, fibroblasts and infiltrating cells (e.g. lymphocytes). Species Crossreactivity: bovine, mouse, Xenopus laevis, and fish. Also reactive with HL-60, HUVEC (human umbilical cord endothelial cell line), BMGE, and 3T3 cells.
