生物活性

Halo tag TMR is a red fluorescent dye composed of Halo tag ligand molecules and TMR. Halo tag can quickly and stably covalently bind to Halo protein with high specificity and affinity[1].

体外研究
(In Vitro)

指南 (以下是我们推荐的方案,本方案仅提供指南,应根据您的具体需要进行修改)。
染色步骤[1]
1) 用编码目的 HaloTag 融合蛋白的质粒转染细胞,并在合适条件下培养至所需汇合度。
2) 取 1/5 体积的培养基替换为 5× HaloTag TMR 工作液,使最终浓度为 5 μM。通过轻轻晃动培养容器混匀。
3) 将细胞置于 37°C、CO2 培养箱中孵育 15 min,使配体与 HaloTag 蛋白发生共价结合。
4) 对于透膜配体:移除含配体的培养基,用等体积预热的新鲜培养基替换,重复此洗涤步骤两次,共洗涤三次。对于细胞表面标记 (非透膜配体):用新鲜培养基洗涤两次,去除细胞外环境中的多余配体。
5) 将细胞在 37°C 完全培养基中继续孵育 30 min,确保未结合的配体被彻底清除。
6) 用无酚红培养基 (如有) 替换培养基以减少自发荧光。
7) 将细胞转移至适合成像的容器中,利用荧光显微镜进行观察。

Guidelines (The following is our recommended protocol. This protocol is provided as a guide only and should be modified to suit your specific needs).
Staining Steps[1]:
1) Transfect cells with a plasmid encoding the HaloTag fusion protein of interest and grow to desired confluence under appropriate conditions.
2) Replace 1/5 of the culture medium with 5× HaloTag TMR working solution to a final concentration of 5 μM. Mix by gently shaking the culture vessel.
3) Incubate cells in a 37°C, CO2 incubator for 15 min to allow covalent binding of the ligand to the HaloTag protein.
4) For permeable ligands: Remove the medium containing the ligand and replace with an equal volume of pre-warmed fresh medium. Repeat this wash step two more times for a total of three washes. For cell surface markers (non-permeable ligands): Wash twice with fresh medium to remove excess ligand from the extracellular environment.
5) Continue incubating the cells in complete medium at 37°C for 30 min to ensure that unbound ligand is completely removed.
6) Replace the medium with phenol red-free medium (if available) to reduce autofluorescence.
7) Transfer the cells to a container suitable for imaging and observe using a fluorescence microscope.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
