一般描述

肝素主要用于推迟血液的凝固。它在凝血途径中可增强抗凝血酶介导的蛋白酶失活。
肝素钠是一种来自糖胺聚糖家族的硫酸化多糖,在细胞培养、癌症生物学和药物发现研究中发挥着至关重要的作用。它对蛋白质和细胞相互作用的影响使其对于研究分子和细胞过程、肿瘤建模、探索结合相互作用以及作为支持细胞活力的细胞培养补充剂很有价值。

应用

  • 来自猪肠粘膜的肝素钠盐已用于从人血浆中纯化sLRP(可溶性循环低密度脂蛋白受体相关蛋白-1)。
  • 它已被用作用于培养人脐静脉内皮细胞的M199培养基中的一种补充剂。
  • 它在血液分离的过程中被用作抗凝血剂。

特点和优势

  • 高纯度化合物适用于各种研究应用

  1. How is Heparin sodium salt from porcine intestinal mucosa, Product H3149, solubilized?

    Heparin sodium salt from porcine intestinal mucosa is soluble in deionized water at a concentrationi of 50 mg/mL.

  2. How much of Heparin sodium salt from porcine intestinal mucosa, Product H3149, is used for cell culture?

    Solutions at 0.5 mg per mL were tested in cell culture. Start at this concentration, and titer from there to determine the optimal concentration for usage.

  3. How are solutions Heparin sodium salt from porcine intestinal mucosa, Product H3149, stored?

    Solutions can be stored at 2-8C for up to 2 years, if sterile filtered through a 0.22 micron filter. Benzyl alcohol (0.06-1%) can be added to solutions to prevent microbial growth.

  4. How many milligrams of Heparin sodium salt, Product H3149, are in the bottle?

    The potency, in units/mg, is lot-specific; the value can be found on the certificate of analysis. It is typically over 140 units per mg. The number of milligrams can be calculated by dividing the number of units by the potency in units per mg.

  5. What is the molecular weight of Heparin sodium salt?

    Heparin is a mixture of polyanion chains having molecular weights ranging from 6,000 to 30,000 Daltons, with most chains in the range of 17,000 to 19,000 Daltons.

  6. How much Heparin sodium salt, is used to prevent coagulation?

    We suggest using 20 to 50 units per mL of blood.

  7. What is the best way to sterilize Heparin sodium salt?

    Although solutions may be autoclaved at 121 °C for 5 to 10 minutes, we generally recommend sterile filtration. This is because prolonged autoclaving may have an effect on its activity.  

  8. What concentration of Heparin sodium salt, can I use to inhibit RNAse activity?

    Heparin has been used at concentrations ranging from 100 to 500 μg/mL. This has been reported in the J. Biol. Chem., 248, 2095 (1973).

  9. 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.

  10. 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.

The majority of histones are replaced by protamines during spermatogenesis, but small amounts are retained in mammalian spermatozoa. Since nucleosomes in spermatozoa influence epigenetic inheritance, it is important to know how histones are distributed in the sperm genome. Conflicting data
