A53-BslashA2_HRP_cytokeratin19_Antibody_051018
Western blot analysis of 15 µg cell lysates from HaCaT (positive control) and Daudi (negative control) cells. Samples were resolved by electrophoresis (4-20% Tris-glycine gel), transferred to nitrocellulose, and probed with 0.1 and 0.5 µg/ml Direct-Blot™ HRP, or 0.5 µg/ml purified anti-Cytokeratin 19 antibody, clone A53-B/A2. Direct-Blot™ HRP anti-GAPDH was used as a loading control (Cat. No. 649203, 1:1000 dilution).

Description

Cytokeratin 19, also known as keratin 19, is a type I intermediate filament protein with a molecular weight of approximately 40-44 kD. Cytokeratin 19 is a heterotetramer composed of two type I and two type II keratin subunits. Unlike other cytokeratins, cytokeratin 19 lacks a C-terminal non-helical extension. This cytokeratin is widely expressed in the periderm (transient superficial layer enveloping developing epidermis), muscle, intestine, bile duct, esophagus, stomach, and thymus. Cytokeratin 19 can be upregulated by vitamin A and is thought to play a critical role in embryogenesis. Cytokeratin 19 intereacts with the pinin protein and has been shown to be modified by phosphorylation (Ser10, Ser35).

Application

WB - Quality tested

Recommended Usage

Each lot of this antibody is quality control tested by Western blotting. For Western blotting, the suggested use of this reagent is 0.1-0.5 µg per ml (1:1000-1:5000 dilution). It is recommended that the reagent be titrated for optimal performance for each application.

25 µl and 100 µl of Direct-Blot™ HRP antibody can be used for approximately 5 and 20 Western blots, respectively, at the recommended concentration/dilution.

Application Notes

Additional reported applications (for the relevant formats) include: immunoprecipitation, immunohistochemistry of paraffin-embedded sections, immunocytochemistry, and ELISA.
