IBA LifeSciences MagStrep type3 Strep-Tactin beads (2ml) are magnetic beads (5% suspension) to purify biotinylated proteins
MagStrep “type3” Strep-Tactin beads have an agarose surface coated with the streptavidin variant Strep-Tactin and intended for purification of biotinylated proteins. Originally, Strep-Tactin was developed for binding and purification of Strep-tagII/Twin-Strep-tag proteins. Strep-Tactin still has the capability to bind biotin, which is used as specific competitor for elution of Strep-tagged proteins. The release is carried out under mild and physiological conditions by adding an excess of free biotin. This reversible binding to Strep-Tactin make them to a perfect tool for isolation of biotinylated proteins or complexes via pull-downs or co-immunoprecipitation (Co-IP) in batch format or high-throughput screenings.Due to the magnetic core no centrifugation step is required since the beads can be easily separated with a magnetic separator, reducing the risk of disturbing the pellet or loss of beads within the wash step to zero. 20 μl suspension correspond to 1 μl magnetic beads.
SUPERTECHS INC TDT CONTROL CELL SUSPENSION
Supertechs Cat# 9500 is a fixed (paraformaldehyde) cell suspension containing human lymphoblastoid REH (TdT⁺) and RA-1 (TdT⁻) cells with stable TdT antigen. This cell suspension can be used as a control for TdT flow cytometric determinations. The control cell suspension contains a mixture of approximately 50% TdT⁺ and 50% TdT⁻ cells at a concentration of 2 x 10⁷ cells/mL (1.0 mL, ~20 tests) in a convenient dropper bottle. Our stabilized cell suspension has a shelf life of about 3 months after preparation when stored at 4°C. Control cells can be used for setting the threshold and gating in flow cytometry studies and for training technicians in performing and evaluating TdT flow cytometry experiments.

LifeSensors Tandem Ubiquitin Binding Entities (TUBE1) Magnetic 1mL
Tandem Ubiquitin Binding Entities (TUBEs) have been developed for the isolation and identification of ubiquitylated proteins. TUBEs display up to a 1000-fold increase in affinity for polyubiquitin moieties over the single ubiquitin binding associated domain (UBA). In addition, TUBEs protect polyubiquitinated proteins from deubiquitination and proteasomal degradation, allowing for detection at relatively low abundance. These properties effectively allow TUBEs to “capture” protein in its polyubiqutinated state. TUBEs can be used to isolate, enrich, and identify ubiquitinated proteins from cell and tissue extracts. Magnetic beads coupled to TUBE 1 allow for efficient recovery of polyubiquitinated proteins in a single step without centrifuge. The magnetic TUBEs allows more complete removal of the unbound supernatant, which leads to lower background. Polyubiquitinated proteins can easily be separated from TUBEs for proteomic studies or identification by Western blotting.
Dojindo Molecular Technologies Inc Cell Counting Kit-8 (CCK-8, 500 tests), cell viability detection in cell proliferation and cytotoxicity assays
DOJINDO is the original creator of WST dyes and Cell Counting Kit-8 (CCK-8). CCK-8 has been used by researchers all over the world for over 20 years. The reasons for this include 1) reliable and stable quality, 2) long-term stability (1 year: 0-5°C, 2 years: -20°C), 3) higher sensitivity than MTT, XTT, MTS, or WST-1, and 4) low toxicity to cells, a combination of features that have been improved over its long history and that no other company can imitate. CCK-8 enables sensitive colorimetric assays to determine cell viability in cell proliferation and cytotoxicity assays. The kit includes Dojindo's WST-8 which is reduced by dehydrogenase activity in cells to give a yellow-colored formazan dye. The amount of the dye, generated by the activity of dehydrogenases in cells, is directly proportional to the number of living cells. visit the supplier website at “https://dojindo.com/product/cell-counting-kit-8/”.
