    Antibody concentration after reconstitution 1 mg/ml.
    Storage after reconstitution The reconstituted solution can be stored at 4°C, protected from the light, for up to 1 week. For longer periods, small aliquots should be stored at -20°C. Avoid multiple freezing and thawing. Centrifuge all antibody preparations before use (10000 × g 5 min).
    Control antigen storage before reconstitution Lyophilized powder can be stored intact at room temperature for two weeks. For longer periods, it should be stored at -20°C.
    Control antigen reconstitution 100 µl double distilled water (DDW).
    Control antigen storage after reconstitution -20°C.
    Preadsorption Control 1 µg peptide per 1 µg antibody.
    Standard quality control of each lot Western blot analysis (unlabeled antibody #ACC-330), and immunohistochemical staining (labeled antibody).

    Scientific background

    CHERP (calcium homeostasis endoplasmic reticulum protein) is a ubiquitously expressed integral sarco/endoplasmic reticulum (SR/ER) membrane protein. CHERP protein consist of 916 amino acid in humans and its structure containing a Pro-rich region and a segment of Arg-Ser dipeptide repeats (an RS domain) near the C terminus, and an RNA recognition motifs (RRMs)1-3.

    CHERP acts as a regulator of both major families of endoplasmic reticulum Ca2+ channels, inositol 1,4,5-trisphosphate receptors (IP3Rs) and ryanodine receptors (RyRs). CHERP is responsible for the regulation of intracellular Ca2+ mobilization in human cells and is involved in neuroblastoma cell proliferation, apoptosis and tumorigenicity1,2.

    CHERP co-localizes with IP3 receptors throughout the cytoplasmic and perinuclear regions in human erythroleukemia cells and in Jurkat cells. CHERP is also detected in the nucleoplasm with prominent accumulation at nuclear speckles1,2. CHERP co-localizes with endogenous ryanodine receptor type 1 (RyR1) in the sarcoplasmic reticulum of rat soleus muscle. Studies of CHERP knockdown reveal decreased intracellular Ca2+ mobilization, cell growth and proliferation2,3.

    Anti-CHERP Antibody (#ACC-330) is a highly specific antibody directed against an epitope of the mouse protein. The antibody can be used in western blot analysis. It has been designed to recognize CHERP from human, rat, and mouse samples.

    Anti-CHERP-ATTO-594 Antibody (#ACC-330-AR) is directly labeled with an ATTO-594 fluorescent dye. ATTO dyes are characterized by strong absorption (high extinction coefficient), high fluorescence quantum yield, and high photo-stability. The ATTO-594 fluorescent label belongs to the class of Rhodamine dyes and can be used with fluorescent equipment typically optimized to detect Texas Red and Alexa-594. Anti-CHERP-ATTO-594 Antibody is specially suited to experiments requiring simultaneous labeling of different markers.
