Product Description
Dickkopf related protein 1 (Dkk-1) is the founding member of the Dickkopf family of proteins that includes Dkk-1, -2, -3, -4, and a related protein, Soggy. Dkk proteins are secreted proteins that contain two conserved cysteine-rich domains separated by a linker region. Each domain contains ten cysteine residues . Mature human Dkk-1 is a 40 kDa glycosylated protein that shares 86%, 87%, 90% and 91% aa sequence identity with mouse, rat, rabbit and bovine Dkk-1, respectively. It also shares 42% and 36% aa identity with human Dkk-2 and Dkk-4, respectively. Dkk-1 and Dkk-4 are well documented antagonists of the canonical Wnt signaling pathway. This pathway is activated by Wnt engagement of a receptor complex composed of the Frizzled proteins and one of two low-density lipoprotein receptor-related proteins, LRP5 or LRP6 . Dkk-1 antagonizes Wnt by forming ternary complexes of LRP5/6 with Kremen1 or Kremen2. Dkk1/LRP6/Krm2 complex internalization has been shown to down-regulate Wnt signaling. Dkk-1 is expressed throughout development and antagonizes Wnt-7a during limb development. Other sites of expression include developing neurons, hair follicles and the retina of the eye .

| Physical Appearance |
Sterile Filtered White lyophilized (freeze-dried) powder. |
| Purity |
> 90% by SDS-PAGE. |
| Biological Activity |
Measured by its ability to inhibit Wnt3a-induced alkaline phosphatase production by C3H10T1/2 cells. The ED50 for this effect is approximately 0.1-0.4 μg/mL in the presence of 10 ng/mL of mouse Wnt3a. |
| Endotoxin |
< 1.0 EU per 1μg of the protein by the LAL method. |
| Formulation |
Lyophilized from a 0.2 μm filtered concentrated solution in PBS, pH 7.4. |
| Reconstitution |
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at ≤ -20°C. Further dilutions should be made in appropriate buffered solutions. |
Shipping and Storage
The products are shipped with ice pack and can be stored at -20℃ to -80℃ for 1 year.
Recommend to aliquot the protein into smaller quantities when first used and avoid repeated freeze-thaw cycles.
Cautions
1. Avoid repeated freeze-thaw cycles.
2. For your safety and health, please wear lab coats and disposable gloves for operation.
3. For research use only.

文献和实验的作用是调控基因表达。例如组蛋白甲基化多导致基因沉默，去甲基化则相反；乙酰化一般是转录激活，去乙酰化则相反。当然，也可在此基础上产生复杂的生物学效应。例如组蛋白去乙酰化酶 HDAC 可影响免疫系统；H3K4me3、H3K9me2 能够调控记忆的形成, 而且 H3K 甲基化与 X 染色体失活、基因组印记和异染色质形成有关；H3 乙酰化通过多种机制调控以来 ATP 的染色质重塑 ，并参与炎症反应；H2A、H2B 泛素化则与 DNA 损害反应有关；而 H3S28 磷酸化与 H3K27 乙酰化可激活转录

扫描仪中，都采用机械式的二维X，Y线性扫描技术实现，即X，Y方向都采用直线驱动器和直线导轨实现往复运动。此类装置，由于驱动系统的频率限制，驱动器的扫描惯性大，使得扫描效率低，分析时间相当长；并且往复行程长，对直线导轨的精度要求相当高。二、光机结合的二维扫描系统为同样实现生物芯片的二维扫描，我们的实验装置设计如图2，采用了振镜和大数值孔径的远心f-è物镜相结合实现X方向扫描，Y方向的运动仍采用直线驱动器和直线导轨实现。 系统中，对于f-è物镜，满足x＝2fè（è为振镜的摆动角度，f为物镜焦距）的线性
