Größe

£1,112.00

SKU:: Z0750-02B-ML650
Reinheit:: Purified by immunoaffinity chromatography.
Lagerbedingungen:: 4°C Do Not Freeze
Hersteller:: United States Biological
Host:: Rabbit
Immunogen:: A 69kD fusion protein corresponding to aa463-1109 of human ZO-1 cDNA. This sequence lies from the N-terminal to the 80aa region (the alpha-motif) present in the a+isoform but absent in the alpha- isoform due to alternative splicing.
Format:: Supplied as a liquid in PBS, pH 7.2. No preservatives added. Labeled with MaxLight™650.
Weitere Details:: MaxLight™ 650 is a new Far-IR stable dye conjugate comparable to Alexa Fluor™647, DyLight™649, Cy5™ and offers better labeling efficiency, brighter imaging and increased immunodetection. Absorbance (655nm); Emission (676nm); Extinction Coefficient 250,000. ZO-1 is a peripheral membrane protein that is associated with tight junctions (zonula occludentes) which are found on the cytoplasmic surface of epithelial and endothelial cell membranes. ZO-1 has a MW of 225kD and is found in two isoforms that differ by the presence or absence of an 80 amino acid region known as 'motif-a'. These two isoforms are the basis for determining two classes of tight junctions. ZO-1 is known to interact with ZO-2. ZO-1 is homologous to dlg, the Drosophila tumor suppressor. Both are members of a putative signal transduction protein family whose members contain a SH3 domain and a domain homologous to the enzyme guanylate kinase. Applications: Suitable for use in FLISA, Western Blot, Immunoprecipitation, Immunofluorescence and Immunohistochemistry. Other applications have not been tested. Recommended Dilutions:. Immunohistochemistry: Frozen sections Immunohistochemistry: For formalin fixed, paraffin embedded tissue sections. Protease XIV pretreatment is required Optimal dilutions to be determined by the researcher. Positive Controls for Immunoprecipitation: Canine MDCK and human Caco-2 cells. Storage and Stability: Store product at 4°C in the dark. DO NOT FREEZE! Stable at 4°C for 12 months after receipt as an undiluted liquid. Dilute required amount only prior to immediate use. Further dilutions can be made in assay buffer. Caution: MaxLight™650 conjugates are sensitive to light. For maximum recovery of product, centrifuge the original vial prior to removing the cap. Note: Applications are based on unconjugated antibody.
