Sample Preparation Kits

Preparation of nuclear extracts is the first step in examining transcription factor activity. Cayman's Nuclear Extraction Kit is formulated for the quick and simple isolation of nuclear and cytoplasmic fractions from cultured cells and tissue homogenates that can be used successfully in Cayman's Transcription Factor...

Strep-Tactin(R) Sepharose(R) is a 4% agarose coupled with the streptavidin variant Strep-Tactin(R) and applicable for purification of Strep-tag(R)II or Twin-Strep-tag(R) fusion proteins. Due to the low concentrated agarose, it is particularly suitable for large proteins, especially if the affinity to...

Indomethacin is a cyclooxygenase (COX) inhibitor that prevents ex-vivo Thromboxane B2 formation and other prostaglandins that can not be prevented using anticoagulant alone. The samples have to be transferred in Indomethacin sampling tubes as soon as possible after blood collection. For measuring some...

Exosomes are nanoscale (30-150 nm), membrane-bound vesicles secreted by cells into the extracellular space, functioning as pivotal mediators in intercellular communication. They facilitate the transfer of proteins, lipids, and nucleic acids, including RNA species, between cells. This vesicular transport mechanism is...

Strep-Tactin(R)XT 4Flow(R) cartridges contain a 4% agarose coupled with the streptavidin variant Strep-Tactin(R)XT and are applicable for purification of Strep-tag(R)II or Twin-Strep-tag(R) fusion proteins with HPLC/FPLC devices like Äkta(R) systems (Cytiva). Due to the broad pH compatibility, excellent pressure...

Strep-Tactin(R)XT 4Flow(R) high capacity columns contain a 4% agarose coupled with the streptavidin variant Strep-Tactin(R)XT and are applicable for purification of Strep-tag(R)II or Twin-Strep-tag(R) fusion proteins via gravity flow. Due to the broad pH compatibility, excellent pressure stability, outstanding...

MagStrep(R) Strep-Tactin(R)XT beads can be used for the purification of strep-tagged fusion proteins in batch in single or high-throughput format. For cell purification we offer specific magnetic beads with a smaller diameter (1µm) and for biotinylated proteins we recommend our MagStrep(R) Strep-Tactin(R) beads....

Ready-to-use Strep-Tactin(R)XT coated microplate (12 x 8-well strips) for ligand binding assays, immuno assays, enzyme assays, or diagnostic assays under high-throughput conditions. Due to the high specificity and affinity (nM-pM) of the streptavidin variant Strep-Tactin(R) XT, Strep-tag(R)II or Twin-Strep-tag(R)...

Strep-Tactin(R)XT 4Flow(R) high capacity Spin Column Kit is perfectly suitable for rapid purification of Strep-tag(R)II and Twin-Strep-tag(R) fusion proteins from multiple small samples in parallel. The kit contains ready-to-use wash buffer as well as elution buffer, Strep-Tactin(R)XT 4Flow(R) high capacity resin...

Strep-Tactin(R)XT 4Flow(R) Starter Kit contains all essential reagents required for purification and detection of Strep-tag(R)II and Twin-Strep-tag(R) fusion proteins. It provides a Strep-Tactin(R)XT 4Flow(R) column, Buffer W, Buffer BXT, and Buffer XT-R for purification as well as Strep-Tactin(R) HRP for subsequent...

Strep-Tactin(R) Magnetic Microbeads are microspheres covalently linked to Strep-Tactin(R). They are suitable for labeling antigen-specific cytotoxic T cells (MHC I Streptamer(R)) or surface marker-specific cells (Fab-TACS(R)/Nano-TACS(R)). To target specific cells, MHC I complexes, low affinity Fab fragments or...

Strep-Tactin(R) Sepharose(R) columns contains 4% agarose coupled with the streptavidin variant Strep-Tactin(R) and are applicable for purification of Strep-tag(R)II or Twin-Strep-tag(R) fusion proteins via gravity flow.
