一般描述

其中的核内蛋白提取方法步骤可使细胞在低渗缓冲液中膨胀。随后细胞破碎，细胞质成分去除，核内蛋白质在高盐缓冲液条件下释放出来。

应用

NXTRACT试剂盒用于研究盐对降压性盐皮质激素治疗小鼠心脏差异基因表达和冠状动脉病变的影响。它还用于测试穿心莲内酯在治疗子宫内膜异位症方面的潜在作用。

其他说明

此试剂盒包含一套从哺乳动物组织或培养细胞制备细胞核和细胞质蛋白提取物的完整系统。所有提取所需的试剂均包含在内。
用于免疫检测的推荐抗体L1293, N2662, AMAB90549
通过详细技术公告中的大量操作流程，可实现特定应用最适合的选择。 例如，可选择含去垢剂和不含去垢剂的核蛋白提取程序，或者适用于大多数细胞类型的标准低渗裂解缓冲液及适用于脆弱细胞的等渗裂解缓冲液。 此外，该试剂盒还提供了通过稀释缓冲液从核提取物中减少盐分的操作流程。 NuCLEAR可灵活满足您的理想蛋白提取需求。 可在2小时内制出提取物，且由于核提取物与细胞质提取物之间几乎不存在交叉污染，因此纯度很高。

  1. Which document(s) contains shelf-life or expiration date information for a given product?

    If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

  2. What are the options for lysis of my cells to make extracts when using Product NXTRACT, CelLytic™ NuCLEAR™ Extraction Kit?

    The use of detergent will lead to maximum protein yield. However we find that the hypotonic lysis is extremely effective and in addition for very fragile cells we offer an isotonic lysis option.

  3. Can Product NXTRACT, CelLytic™ NuCLEAR™ Extraction Kit, be used to make nuclear protein extracts for EMSAs/DNA binding studies?

    Several references describe the use of the N-XTRACT kit in sample preparation for EMSA work.1. Xie, J., et al., β2-Microglobulin as a negative regulator of the immune system: high concentrations of the protein inhibit in vitro generation of functional dendritic cells. Blood, 101(10), 4005-4012 (2003).2. Marambaud, P., et al., A CBP Binding Transcriptional Repressor Produced by the PS1/ε-Cleavage of N-Cadherin Is Inhibitedby PS1 FAD Mutations. Cell, 114, 635-645 (2003).3. Chen, G., et al., Phosphorylated FADD induces NF-κB, perturbs cell cycle, and is associated with poor outcome in lung adenocarcinomas. Proc. Nat. Acad. Sci. USA, 102(35), 12507-12512 (2005).

  4. Is Product NXTRACT, CelLytic™ NuCLEAR™ Extraction Kit, suitable for use on tissues? 

    We have used the kit with several tissues: Mouse lung and brain, Rat liver and Rabbit muscle. For these tissues we usually used the kit with 100 mg tissue. After extraction with 140 μl Extraction buffer, we obtained an average yield of protein concentration as follows: 3.2 mg/ml for brain, 4.1 mg/ml for lung, 3.3 mg/ml for muscle and 10 mg/ml for liver.

  5. When using Product NXTRACT, CelLytic™ NuCLEAR™ Extraction Kit, what can I use for the mechanical lysis of my cells?

    We recommend the use of a glass tissue homogenizer, with a type B pestle, or alternatively a syringe with a narrow-gauge (No. 27) hypodermic needle may be used.

  6. How "pure" is the nuclear extraction using Product NXTRACT, CelLytic™ NuCLEAR™ Extraction Kit? 

    It is important to keep in mind that this kit will provide a crude nuclear fraction.  Depending on the care taken at the step where the nuclei are pelleted and the supernatant containing the cytoplasmic fraction is removed, we have found that the cytoplasmic contamination of the nuclear pellet may be a few percent.

  7. How do I get lot-specific information or a Certificate of Analysis?

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.

  8. How do I find price and availability?

Granulocyte-macrophage colony-stimulating factor (GM-CSF) and macrophage colony-stimulating factor (M-CSF) independently stimulate the proliferation and differentiation of macrophages from bone marrow progenitor cells. Although the GM-CSF and M-CSF receptors are unrelated, both couple to Ras-dependent signal transduction pathways, suggesting that these
