  • Angelman Syndrome

    Angelman Syndrome is characterized by severe developmental delay, speech impairment, gait ataxia and/or tremulousness of thelimbs, and a unique behavioral phenotype that includes happy demeanor and excessive laughter. In principle, its resulted from the deregulation of UBE3A gene located on chromosome 15. Here we present a brief introduction to the common knowledge of Angelman Syndrome.

  • Antibody Pair for Proximity Ligation Assay

    The in situ proximity ligation assay is a powerful technology capable of detecting single protein events such as protein protein interactions (e.g. protein dimerization) and modifications (e.g. protein phosphorylation) in tissue and cell samples prepared for microscopy. Each detected signal is visualized as an individual fluorescent dot, these signals can be quantified (counted) and assigned to a specific subcellular location based on microscopy images.

  • Anti-PEG Antibody Pair

    Polyethylene Glycol (PEG) is a long chain polymer that has been approved by the Food and Drug Administration for human intravenous, oral and dermal applications. Covalent attachment of PEG (PEGylation) to proteins can reduce their immunogenicity, minimize proteolytic cleavage and increase their serum half-life. PEG has also been attached to small molecules and liposomes for more selective delivery. PEG-modification of superparamagnetic iron oxide and quantum dots can improve their biocompatibility and reduce non-specific uptake. This video shows the procedure of sandwich ELISA assay for anti-PEG antibody pair.

  • Antibody Purification (Protein A Column)

    Protein A Sepharose is prepared by covalently coupling Protein A to 6% cross-linked sepharose beads. The coupling technique is optimized to give a high binding capacity for IgG. This protocol is a simple, reliable method for purifying total IgG from crude protein mixtures such as serum or ascites fluid.

  • Atomic Force Microscopy(AFM) Basic Tutorial

    Atomic force microscopy (AFM) is a very high-resolution type of scanning probe microscopy, with demonstrated resolution on the order of fractions of a nanometer, more than 1000 times better than the optical diffraction limit. The AFM is one of the foremost tools for imaging, measuring, and manipulating matter at the nanoscale. This video shows the AFM basic tutorial.

  • ApoTox-Glo™ Triplex Assay

    The ApoTox-Glo™ Triplex Assay combines three Promega assay chemistries to assess viability, cytotoxicity and apoptosis within a single assay well. The first part of the assay simultaneously measures two protease activities: GF-AFC is used to measure cell viability, and bis-AAF-R110 to cytotoxicity. The second part of the assay uses the Caspase-GloR to measure caspase activity.

  • alamarBlueR Cell Proliferation Indicator

    alamarBlueR works as a cell viability and proliferation indicator through the conversion of resazurin to resorufin. Resazurin, a non-fluorescent indicator dye, is converted to highly red fluorescent resorufin via reduction reactions of metabolically active cells. The amount of fluorescence produced is proportional to the number of living cells.

  • Antibody Purification (Affinity)

    Cyanogen bromide (CNBr) is the most common method for preparing affinity chromatography to purify antibody because of its simplicity and mild pH conditions. CNBr reacts with the hydroxyl groups on agarose to form cyanate esters and imidocarbonates. These groups are reacted with primary amines in order to couple the protein onto the agarose matrix.
