描述: Ethidium bromide solution is a fluorescent stain for visualising nucleic acids in solution or in electrophoresis gels. The solution is provided at a concentration of 0,625 mg/ml. A final working concentration of 0,5 g/ml is easily obtained by adding one drop of solution to 50 ml of molten agarose, running buffer or staining buffer. Ethidium bromide solution in dropper bottles may be stored at room temperature for up to one year.

描述: Potassium bromide is transparent from the near UV to long wave IR wavelengths. In IR-spectroscopy, solid samples which are difficult to melt or dissolve in any suitable IR-transmitting solvent, are analysed by grinding with potassium bromide powder, and pressing into a disc. This procedure has a high quality demand of the used potassium bromide. Potassium bromide Uvasol® is adjusted to a mean particle size of 150 μm. This is sufficient for the preparation of perfectly good pellets without the need for further pre-treatment and the associated risk of contamination. It also retains its powdery form over a period of years if stored in an airtight condition. Its physical suitability for pelletising is checked by a special application test and its chemical purity established by full spectrum FT-IR analysis.

描述: Blue light transilluminators are often used as an alternative to UV transilluminators when users wish to use ‘safe dyes’ instead of ethidium bromide. A blue light transilluminator is a ‘safe’ light source, in that the user is not exposed to harmful UV radiation, and samples are free from photonicking.

供应商: EBIOSCIENCE

描述: Description: This 6D3 monoclonal antibody reacts with B lymphocyte-induced maturation protein-1 (Blimp-1), a transcriptional repressor expressed in B and T cells. This approximately 90-kDa protein contains five consecutive Kruppel-like zinc finger domains by which it binds DNA. In B cells, Blimp-1 promotes terminal differentiation into antibody-secreting plasma cells during a primary immune response. In addition, Blimp-1 has been implicated in germinal center formation in response to T-dependent and T-independent antigens, as well as in some diffuse large B cell lymphomas. Expressed in CD4+ and CD8+ effector/memory T cells and FoxP3+ regulatory T cells, reports have suggested possible roles for Blimp-1 in T cell homeostasis and suppression of IL-2 production. Moreover, by suppressing Th1 differentiation, Blimp-1 plays a role in T helper cell differentiation. Finally, Blimp-1 has been demonstrated to play a significant role in the terminal differentiation of effector and effector memory CD8+ T cells during viral infection. Applications Reported: This 6D3 antibody has been reported for use in immunoblotting (WB) and immunohistology staining of paraffin-embedded tissue sections. Applications Tested: This 6D3 antibody has been tested by western blot of reduced A20 cell lysates. For western blottiing, this antibody can be used at 1-10 µg/mL. Moreover, this antibody was tested by immunohistochemistry of formalin-fixed paraffin embedded human tonsil tissue. Antigen retrieval was performed using 10mM citrate buffer at pH 6.0. For immunohistochemistry, this antibody can be used at 10 µg/mL. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest. Blimp-1 (B lymphocyte maturation protein-1) is a nuclear protein with five zinc fingers in its carboxy terminus. It is a transcriptional repressor that is both required and sufficient to trigger terminal differentiation of B lymphocytes and monocyte/macrophages. Blimp-1 is expressed in, and may be required for terminally differentiated epithelial cells, retinal neurons and other lineage cells. It has also been implicated in the repression of beta-interferon (IFN-beta) and c-myc gene expression.
