EDQM
The European Directorate for the Quality of Medicines (EDQM) has originated from the European Pharmacopoeia Secretariat which, with the addition of new responsibilities changed its name to the European Department for the Quality of Medicines (EDQM). The EDQM sits alongside the European Medicines Agency (EMEA).
Amongst other activities, the EDQM is responsible for the European Pharmacopeia and the issuing of Certificates of Suitability (CEP).
Certificates of Suitability (CEP) are recognised by all signatory states of the European Pharmacopoeia Convention and by the European Union. Other countries have also chosen to recognise them. In the case of Fetal Bovine Serum and other Bovine Serum a CEP can be used by the manufacturers of Fetal Bovine Serum and other Bovine Serum which is intended for use in the manufacture of pharmaceutical products to demonstrate compliance with the Bovine Serum monographs of the European Pharmacopoeia and the EDQM requirements for substances concerned by TSE risk.
The discovery of Bovine Spongiform Encephalopathy (BSE), which is one of a group of similar infections now referred to as Transmissible Spongiform Encephalopathies (TSEs), and it’s spread over many countries of the European Union as well as its discovery in Canada, the USA and Japan is well known. The European events provided the impetus for the Council of Europe Public Health Committee (CEPHC) to pass Resolution AP-CSP (99) 5 addressing the TSE concerns and creating a Certificate of Suitability (COS) pursuant to Directive 75/318/EEC.
The granting of a CoS to a manufacturer, for a particular product, certifies that the product in question has been assessed for the level of risk of transmission of TSEs, and that the risk level is considered low enough that the product is certified as suitable for use in the manufacture of medicinal products in the European Union.
The process of approval requires the manufacturer to submit a dossier that covers all relevant aspects of the collection of raw material and further processing that is performed to reach the product that is offered to end users. This dossier is detailed and covers the specific material that is collected, the collection method, process validation, testing, traceability, quality systems and an expert review.
Only after this dossier has been examined and approved by two rapporteurs and, if necessary, by a panel of experts appointed by the European Directorate for the Quality of Medicines (EDQM) is the manufacturer granted a COS.
Moregate Biotech has been granted a COS for:
- Fetal Bovine Serum – Australian Origin – CEP2000-187
- Fetal Bovine Serum – New Zealand Origin – CEP2000-188
- Adult Bovine Serum - New Zealand Origin – CEP2001-093
- Adult Bovine Serum (Defibrinated) - New Zealand Origin – CEP2000-174
- Bovine Plasma – New Zealand Origin – CEP2003-199
- Bovine Serum Albumin – manufactured in Australia from New Zealand origin Bovine Plasma – CEP2003-205
- Bovine Plasma – Australian Origin - CEP 2005-192
- Bovine Serum Albumin – manufactured in Australia from Australian origin Bovine Plasma - CEP 2005-191

血浆是由抗凝的血液中分离出来的液体,其中含有纤维蛋白原,若向血浆中加入Ca2+,血浆会发生再凝固,因此血浆中不含游离的Ca2+.血清是由凝固的血中分离出来的液体,其中已无纤维蛋白原,但含有游离的Ca2+,若向其中再加入Ca2+,血清也不会再凝固.此外,血浆与血清的另一个区别是：血清中少了很多的凝血因子,以及多了很多的凝血产物.
各位大神，本人实验室小白一枚，现在要保存乙肝病人的血清，以后用来做实验感染细胞。为了最大限度保持病毒的感染活力，应该怎么保存呢？直接-80度冷冻可以吗？需要加甘油吗？
血清的基本成分是水，水中溶有蛋白质、脂肪、糖、无机盐、维生素等营养成分，也溶有人体代谢产物。血清中有抗体，这是被称作免疫球蛋白的蛋白质。
你说的应该称抗毒血清。
因制作时是将蛇毒、病原菌产的毒等小量多次地注射到免子、马血管内，每日慢慢加大注射量，一定时间后，因该动物体内产生抗体，经检测，达到一定效价后，就可以抽血。血液分离血清后再经提纯，就成了抗毒血清。
如蛇、白喉、破伤风、狂犬病抗毒血清等都是如此制备，用来治疗相应毒素反应。
该生物制剂是异种血清，对人会有过敏反应，注射前均要做皮试。阴性可注射，阳性必需作脱敏疗法才行。
1)提供基本营养物质：氨基酸、维生素、无机物、脂类物质、核酸衍生物等，是细胞生长必须的物质。
2)提供结合蛋白：结合蛋白作用是携带重要地低分子量物质，如白蛋白携带维生素、脂肪、以及激素等，转铁蛋白携带铁。结合蛋白在细胞代谢过程中起重要作用。
3)提供激素和各种生长因子：胰岛素、肾上腺皮质激素(氢化可的松、地塞米松)、类固醇激素(雌二醇、睾酮、孕酮)等。生长因子如成纤维细胞生长因子、表皮生长因子、血小板生长因子等。
4)对培养中的细胞起到某些保护作用：有一些细胞，如内皮细胞、骨髓样细胞可以释放蛋白酶，血清中含有抗蛋白酶成分，起到中和作用。这种作用是偶然发现的，现在则有目的的使用血清来终止胰蛋白酶的消化作用。因为胰蛋白酶已经被广泛用于贴壁细胞的消化传代。血清蛋白形成了血清的粘度，可以保护细胞免受机械损伤，特别是在悬浮培养搅拌时，粘度起到重要作用。血清还含有一些微量元素和离子，他们在代谢解毒中起重要作用，如SeO3,硒等
5)提供促接触和伸展因子使细胞贴壁免受机械损伤。
6)血清中有抗体，这是被称作免疫球蛋白的蛋白质，血清可以抗病毒,增强抵抗力血清属于生物制剂。
