    7-Xylosyltaxol B Description
    Source: The branches and leaves of Taxus wallichiana var.mairei.
    Biological Activity or Inhibitors:
    Solvent: Pyridine, Methanol, Ethanol, etc.
    Storage: Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months(2-8C).

    Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20C. Generally, these will be useable for up to two weeks. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.

    Need more advice on solubility, usage and handling? Please email to: service@chemfaces.com

    After receiving: The packaging of the product may have turned upside down during transportation, resulting in the natural compounds adhering to the neck or cap of the vial. take the vial out of its packaging and gently shake to let the compounds fall to the bottom of the vial. for liquid products, centrifuge at 200-500 RPM to gather the liquid at the bottom of the vial. try to avoid loss or contamination during handling.

    Efficient expression of single chain variable fragment antibody against paclitaxel using the Bombyx mori nucleopolyhedrovirus bacmid DNA system and its characterizations.[Pubmed: 26940321]
    A single chain variable fragment (scFv), the smallest unit of functional recombinant antibody, is an attractive format of recombinant antibodies for various applications due to its small fragment and possibility of genetic engineering. Hybridoma clone 3A3 secreting anti-paclitaxel monoclonal antibody was used to construct genes encoding its variable domains of heavy (VH) and light (VL) chains. The VH and VL domains were linked to be the PT-scFv3A3 using flexible peptide linker in a format of VH-(GGGGS)5-VL. The PT-scFv3A3 was primarily expressed using the pET28a(+) vector in the Escherichia coli system, and was then further expressed by using the Bombyx mori nucleopolyhedrovirus (BmNPV) bacmid DNA system. Interestingly, the reactivity of PT-scFv3A3 expressed in the hemolymph of B. mori using the BmNPV bacmid DNA system was much higher than that expressed in the E. coli system. Using indirect competitive enzyme-linked immunosorbent assay (icELISA), the PT-scFv3A3 (B. mori) reacted not only with immobilized paclitaxel, but also with free paclitaxel in a concentration-dependent manner, with the linear range of free paclitaxel between 0.156 and 5.00 μg/ml. The PT-scFv3A3 (B. mori) exhibited less cross-reactivity (%) than its parental MAb clone 3A3 against paclitaxel-related compounds, including docetaxel (31.1 %), 7-xylosyltaxol (22.1 %), baccatin III (<0.68 %), 10-deacetylbaccatin III (<0.68 %), 1-hydroxybaccatin I (<0.68 %), and 1-acetoxy-5-deacetylbaccatin I (<0.68 %). With the exception of cephalomannine, the cross-reactivity was slightly increased to 8.50 %. The BmNPV bacmid DNA system was a highly efficient expression system of active PT-scFv3A3, which is applicable for PT-scFv3A3-based immunoassay of paclitaxel. In addition, the PT-scFv3A3 can be applied to evaluate its neutralizing property of paclitaxel or docetaxel toxicity.
