This product consists of 6 linear double-stranded DNA fragments, with sizes ranging from 100 bp to 2000 bp, specifically 100 bp, 250 bp, 500 bp, 750 bp, 1000 bp, and 2000 bp. The 750 bp band is highlighted with a concentration 2.5 times higher than the other bands, facilitating observation after electrophoresis.2. In 5 ul of this product, the content of the regular bands is approximately 30 ng, while the highlighted band contains about 75 ng.3. The product is preserved in 1x Loading Buffer and can be directly used for electrophoresis, making it convenient to use.4. This product is not suitable for polyacrylamide gel electrophoresis.Recommended Electrophoresis Buffer and Agarose Gel Concentration:This product is recommended to be used with 1x TAE electrophoresis buffer, with a suggested agarose concentration of 1.5% to 2.0%. For electrophoresis of smaller fragments, it is recommended to use GelRed nucleic acid dye.Usage Instructions:1. Prepare an agarose gel containing a nucleic acid dye, such as EB or GelRed.2. The concentration of the agarose gel has a significant impact on DNA electrophoresis. The recommended agarose gel concentration for this product is 1.5% to 2.0%.3. It is suggested to use 1x TAE buffer, with an electrophoresis voltage not exceeding 10 v/cm.4. For common 3.5 mm sample wells, a loading volume of 3 to 5 ul is recommended, with an appropriate increase for wider gel wells.5. Run the electrophoresis to the appropriate distance: For nucleic acid dyes such as EB, Goldview, and GRBlue, the bromophenol blue front should not exceed two-thirds of the gel, otherwise, smaller fragments may weaken due to the detachment of the nucleic acid dye from DNA. For dyes like GelRed, longer distances can be used as long as the smallest fragment does not run out of the gel. Generally, the bromophenol blue indicator band should be at least 1 cm away from the edge of the gel.6. After electrophoresis, observe the bands under a UV lamp.7. The 5x Loading Buffer included in the product is used for mixing with the samples to be tested before loading, containing both bromophenol blue and xylene cyanol as indicators.Product componentD665544Component100 T500TStorageD665544ADNA Ladder (100-2000bp)500 µL5× 500 µL-20℃.

Binds two different NK cell receptors: CD96 and CD226. These interactions accumulates at the cell-cell contact site, leading to the formation of a mature immunological synapse between NK cell and target cell. This may trigger adhesion and secretion of lytic granules and IFN-gamma and activate cytoxicity of activated NK cells. May also promote NK cell-target cell modular exchange, and PVR transfer to the NK cell. This transfer is more important in some tumor cells expressing a lot of PVR, and may trigger fratricide NK cell activation, providing tumors with a mechanism of immunoevasion. Plays a role in mediating tumor cell invasion and migration. Serves as a receptor for poliovirus attachment to target cells. May play a role in axonal transport of poliovirus, by targeting virion-PVR-containing endocytic vesicles to the microtubular network through interaction with DYNLT1. This interaction would drive the virus-containing vesicle to the axonal retrograde transport... Read More | Purity:>95%, by SDS-PAGE visualized with Coomassie® Blue Staining. Description： 100B, previously called S100 beta, belongs to the S100 family within the EF-hand superfamily of Ca2+ binding proteins.

Description： 100B, previously called S100 beta, belongs to the S100 family within the EF-hand superfamily of Ca2+ binding proteins. S100 proteins contain two EF-hand motifs that differ in affinity, separated by a hinge region with a hydrophobic cleft that is exposed upon Ca2+ binding. S100B is a 91 amino acid (aa) protein, after removal of the initial methionine, and is found as homodimers of 10.4 kDa monomers. Human S100B shares 99%, 98%, 100%, 99% and 97% aa sequence identity with mouse, rat, rabbit, equine and bovine S100B, respectively. Within the S100 family, human S100B shows the highest aa identity (59%) with S100A1. S100B is expressed primarily by astrocytes and oligodendrocytes in the central nervous system, and by Schwann cells in the peripheral nervous system. Ca2+-bound S100B interacts in vitro with at least 20 cytoplasmic proteins, including several structural molecules such as tubulin and GFAP. It can inhibit the phosphorylation of these kinase substrates and others such as tau and neuromodulin. Astrocytes can secrete S100B, which then acts in a cytokine-like manner. Nanomolar concentrations of S100B are secreted constitutively, promote proliferation, and are neurotrophic and anti-apoptotic. Blood levels of S100B reflect extracellular concentrations within the nervous system, and are elevated in Down’s syndrome, Alzheimer’s disease and Tourette’s syndrome, metabolic stress, acute brain injury and brain tumors. Micromolar concentrations of S100B can be destructive and pro-apoptotic; they induce the expression of iNOS, COX-2, IL-1, IL‑6 and TNF-alpha by microglia, astrocytes or neurons. Most extracellular actions of S100B can be mediated by RAGE (receptor for advanced glycation end products), which is also a receptor for other S100 proteins...
