      • Cytosolic Ca2+ has long been known to act as a key second messenger in many intracellular pathways including synaptic transmission, muscle contraction, hormonal secretion, and cell growth and proliferation.1,2 The mechanism controlling the influx of intracellular Ca2+ either by calcium-release-activated Ca2+ channels (CRAC) or from intracellular stores has lately become of great interest.

        Recently, several key players of the store-operated complex have been identified.3 The Orai family consists of three members, Orai1-3, and the STIM family, which consists of two members, STIM1 and STIM2. Orai1 (also known as CRACM1) acts as the store-operated calcium channel (SOC) and STIM1 as the endoplasmic reticulum (ER) Ca2+ sensor.3,4 The majority of STIM1 appears to be localized intracellularly at the ER membrane while low expression of STIM1 has been detected on the cell surface of several cell types.5 STIM1 has an amino-terminal EF hand Ca2+ binding domain facing the lumen of the ER.6 Upon Ca2+ store depletion, STIM1 molecules are redistributed in punctae underneath the plasma membrane and activate SOCs.

        Several possible interactions between STIM1 and Orai1 have been suggested. The most simple and cited is a dynamic interaction between the cytosolic C-terminus of STIM1 and the cytoplasmic domain of the Orai1 channel.7-9 STIM1 is assumed to regulate the activity of all known SOCs, including native SOCs.Consistent with their important role as calcium sensors within the ER, STIM1 proteins are ubiquitously expressed.

    Anti-STIM1 (extracellular) Antibody (#ACC-063) is a highly specific antibody directed against an extracellular epitope of the human Stromal interaction molecule 1. The antibody can be used in western blot, immunocytochemistry, immunohistochemistry, and indirect flow cytometry applications. It has been designed to recognize STIM1 from human, rat, and mouse samples.

    Anti-STIM1 (extracellular)-ATTO-550 Antibody (#ACC-063-AO) is directly labeled with an ATTO-550 fluorescent dye. ATTO dyes are characterized by strong absorption (high extinction coefficient), high fluorescence quantum yield, and high photo-stability. The ATTO-550 fluorescent label is related to the well known dye Rhodamine 6G and can be used with filters typically used to detect Rhodamine. Anti-STIM1 (extracellular)-ATTO-550 Antibody has been tested in immunocytochemistry and immunohistochemistry applications and is especially suited for experiments requiring simultaneous labeling of different markers.

    Discovery Antibodies的Cyclin dependant kinase 2 (CDK2) is a serine/threonine protein kinase which controls both G1/S and G2/M transitions. CDKs along with cyclins and CDK inhibitors regulate cell cycle progression. Specific cyclins activate different CDKs; in early G1, CDK2 pairs with cyclin E to promote entry into the S phase before switching to partner with cyclin A to drive the cell through S phase. Once activated CDKs phosphorylate downstream proteins to initiate signalling cascades. CDK2 phosphorylates and inactivates the RB1 (pRb) tumour suppressor family of proteins.CDK的活动受到严格控制。CDK2活性可以被包括P21在内的一系列抑制剂抑制。细胞周期失调和增殖控制的丧失与细胞转化和癌症密切相关。CDK2在DNA损伤反应(DDR)中的细胞周期停滞中也似乎起着积极作用,它的抑制作用会阻碍DDR,并使细胞对电离辐射敏感,从而诱导细胞死亡。该抗体与AlexaFluor®488偶联。AlexaFluor®488是一种流行的鲜绿色荧光染料,具有高pH稳定性。
