CD8 is a 68 kDa transmembrane glycoprotein expressed as a heterodimer by a majority of thymocytes, and by class I major histocompatibility complex restricted, mature, suppressor/cytotoxic T cells.
The antibody is a useful aid for classification of cytotoxic/suppressor T-cell lymphomas.

CD45 is a transmembrane glycoprotein expressed on most nucleated cells of hematopoetic origin. On human leucocytes, five different isoforms of CD45 have been identified, named ABC, AB, BC, B and 0. This antibody reacts with an epitope unique for CD45R0. The antibody labels most thymocytes, a subpopulation of resting T cells within both CD4 and CD8 subsets, and mature, activated T cells. It is effective on formalin-fixed, paraffin-embedded tissue sections. Results aid in the classification of T-cell neoplasms.

描述
This product is designed for his-tagged protein isolation. High selectivity for poly-histidine tags results in extremely low background levels.
The new bead surface chemistry is Cobalt-based and offers exceptionally fast binding kinetics and a high yield per microliter of beads. The entire protocol (from cleared lysate to purified protein) takes only 20 minutes! The protocol includes instructions for making the required buffers as well as methods for optimizing buffer composition.
Dynabeads® His-Tag Isolation & Pulldown replaces Dynabeads® TALON™. Dynabeads® His-Tag Isolation & Pulldown has a new optimized binding chemistry that offers significant advantages over Dynabeads® TALON™ which were coated in the TALON™ chemistry. This optimization results in a cleaner prep with higher yield of his-tag protein and extremely low background levels.
Dynabeads His-Tag Isolation & Pulldown is designed for isolating His-tagged proteins from cleared lysates. Isolated his-tagged proteins can either be eluted from the beads or kept on the beads for use in bead-based downstream assays. Bead bound his-tagged proteins can be used in various downstream assays such as bait-prey pulldowns, etc.
Note: This product contains Dynabeads and a protocol only, and does not include buffers.
The technology used for the discontinued Dynabeads® TALON™ was licensed from Clontech. TALON™ is a registered trademark of Clontech Laboratories Inc., USA.
