Adult Bovine Serum Defibrinated (ABSD) is obtained from blood taken from cattle deemed fit for human consumption following ante and post mortem veterinary inspection. The blood is collected in slaughter-houses supervised by government veterinarians.
The blood is collected into sanitary buckets and the fibrin is mechanically removed during the clotting process. The liquid component of the blood is pooled and separated using a continuous flow separator before being dispensed into either 5L Bottles or 25L Bladders and immediately frozen.

EP/USP
The European Pharmacopeia consists of a number of general and specific monographs covering various classes of products.
The monographs set out requirements to be met and followed for all products in the class.
Recently the EP has introduced a Monograph for Bovine Serum – Monograph No 04/2006:2262 to be found in E.P. 5.4
This monograph provides a definition of Bovine Serum and sets out details of production, and requirements for viral inactivation parameters, quality control testing, storage conditions and labelling.
Moregate Bovine Serum products meet these requirements and Certificates of Analysis are modeled on the QC test requirements.
The United States Pharmacopeia-National Formulary (USP-NF) contains standards for medicines, dosage forms, drug substances, excipients, medical devices, and dietary supplements.
Within the Pharmacopeia are Monographs and general chapters.
The monographs consist of information such as the ingredient name, definition, packaging and labelling requirements, storage and a specification.
The specifications list tests to be performed along with the procedure to be followed and the acceptable limit.
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 Plasma – Australian Origin - CEP 2005-192
- Bovine Serum Albumin – manufactured in Australia from Australian origin Bovine Plasma - CEP 2005-191
Copies of the Certificates of Suitability are available upon request

血清蛋白是血浆里最丰富的蛋白质。每一个蛋白分子能携带七个脂肪酸分子。这些脂肪酸分子结合在蛋白的缝隙中，它们富含碳的尾部埋藏在里面安全地避开周围的水分子。血清蛋白同样能够携带许多其它的不溶于水的分子。尤其是血清蛋白，能够携带着许多药物分子，比如布洛芬。
正因为血清蛋白是如此普遍地存在于血液中并且如此容易地被提纯，所以它成为科学家最早研究的蛋白质之一。今天，当需要一种蛋白质时，一种来源于牛体内的类似的蛋白在研究中被广泛地使用，这种蛋白叫做牛族血清蛋白或者称作BSA。许多酶在稀溶液中不稳定，解决的办法是加入一些牛族血清蛋白。在试验中它能使酶稳定，且相对地中性,不会影响酶的性质。
想做临床的血标本的一些代谢组学研究，不知道应该用血浆还是血清，大家的说法好像也不太一致，请大神指导啊，最好有些参考文献，谢谢！

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？
纤维蛋白已被除去(如通过血凝或去纤维蛋白法)的血浆
血液凝固析出的淡黄色透明液体。如将血液自血管内抽出，放入试管中，不加抗凝剂，则凝血反应被激活，血液迅速凝固，形成胶冻。凝血块收缩，其周围所析出之淡黄色透明液体即为血清，也可于凝血后经离心取得。在凝血过程中，纤维蛋白原转变成纤维蛋白块，所以血清中无纤维蛋白原，这一点是与血浆最大的区别。而在凝血反应中，血小板释放出许多物质，各凝血因子也都发生了变化。这些成分都留在血清中并继续发生变化，如凝血酶原变成凝血酶，并随血清存放时间逐渐减少以至消失。这些也都是与血浆区别之处。但大量未参加凝血反应的物质则与血浆基本相同。为避免抗凝剂的干扰，血液中许多化学成分的分析，都以血清为样品。（右图为血清蛋白）
作用：
●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。
●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。
●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。
●提供促接触和伸展因子使细胞贴壁免受机械损伤。
●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。
