应用

已有研究采用脱氧核糖核酸钠盐为研究对象，研究了酶抑制剂和吸收促进剂对Caco-2细胞口服鲑鱼降钙素的细胞毒性。已有研究应用脱氧核糖核酸钠盐研究了隐孢子虫卵囊DNA的提取方法。
以鲑鱼睾丸中的脱氧核糖核酸钠盐为基础培养基，对几种 莫氏芽孢杆菌 进行了厌氧生长试验 它还被用作基于微板的基质染色质免疫沉淀(ChIP)的免疫沉淀(IP)缓冲液的组分。
鲑鱼精脱氧核糖核酸(SS-DNA)可用于研究DNA与结合剂、插入剂、修饰剂、检测剂和致密剂的物理化学相互作用。鲑鱼精DNA被用于研究磁性介孔二氧化硅纳米颗粒(M-MSNs)的负载能力和聚合物纳米层结构的结合能力。SS-DNA可作为开发DNA检测方法的底物。

  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. 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.

  3. What is the molecular weight of Product D1626, Deoxyribonucleic acid sodium salt from salmon testes (DNA)?

    The molecular weight for product D1626 has not been determined.  In general, the reference J.A.C.S., vol. 118, 10679 (1996), reports the molecular weight to be 1.3 million or around 2,000 base pairs.

  4. What is the solubility of Product D1626, Deoxyribonucleic acid sodium salt from salmon testes (DNA)?

    Sigma tests solubility in water at 2 mg/mL.  To prevent shearing of the large genomic DNA, this product should be dissolved in water (1 mg/mL) with no sonication or stirring. Gentle inversion overnight at 0-4 °C is recommended to completely solubilize the DNA. The presence of 1 mM EDTA is recommended to prevent nucleases from degrading the DNA.

  5. What is the solution stability of Product D1626, Deoxyribonucleic acid sodium salt from salmon testes (DNA)?

    Solutions of DNA have been stored successfully for several months at 4°C, in 10 mM Tris, pH 7.5 - 8.0, with 1 mM EDTA and without a bacteriostatic agent.

This study shows that DNA (linearized plasmid, 4331 base pairs and salmon sperm, 2000 base pairs, respectively) adsorbs to model membranes of zwitterionic liquid crystalline phospholipid bilayers in solutions containing divalent Ca(2+) cations, and also in solutions containing monovalent Na(+).

The potential of slow-growing mycobacteria to form biofilms in human tissues contributes to the problem of establishing an effective treatment strategy. The purpose of this study was to examine new antibiotic strategies to enhance current treatment options for these infections.

For decades, acyclovir-induced nephrotoxicity was believed to be secondary to crystalluria. Clinical evidence of nephrotoxicity in the absence of crystalluria suggests that acyclovir induces direct insult to renal tubular cells. We postulated that acyclovir is metabolized by the alcohol dehydrogenase
