国产胎牛血清和进口胎牛血清的区别

国产胎牛血清和进口胎牛血清的区别

血清是血液凝固析出的淡黄色透明液体,是血浆去除纤维蛋白原后的混合物。血清的主要成分有蛋白质、氨基酸、糖类和维生素、多肽(如生长因子、胰岛素、促生长激素)等。血清可以在细胞生长时,为细胞提供综合营养、激素、生长和附着因子;血清还可作为细胞培养系统的缓冲液,避免各种因素干扰细胞生长或产生毒性作用。胎牛血清是对4-9月龄胎牛心脏穿刺取血,目前,国产胎牛血清异军突起,和进口胎牛血清相比,有哪些区别呢?


1. 质量标准不同:国外的血清,划分为胎牛血清、小牛血清、新生牛血清,根据质量评价标准,不同的血清,划分为标准特级 等等级 ,根据科研、生产的不同,提供不同的产品。国产血清通常缺乏国外的这种评价标准。

2. 质量检测内容不同:在国外,胎牛血清的检测至少需要进行9种外源病毒的检测,还需要对蛋白质、脂质、微量元素和维生素等的检测,而我国的血清检测只明文规定了对牛腹泻病毒的检测,而对于其他的检测,没有做官fang要求。

3. 病毒灭活方法和验证方法不同:一定剂量的伽马射线照射可灭活全部细菌、支原体和部分病毒。无论采用何种病毒灭活方法,均应进行工艺验证 ,并摸索出最佳辐照剂量。在病毒灭活工艺验证过程中,加入的指示病毒应包括脂包膜和非脂包膜病毒 、DNARNA病毒。但是,我国绝大部分病毒性疫苗生产使用的是未经病毒灭活处理的牛血清,也缺乏验证方法,给各项研究带来了不便。

地区来源:新西兰;

物种来源:;

内毒素水平:≤ 20 EU/mL;

血红素水平:< 25mg/dL;

热灭活:未灭活;

详细介绍:Enhance growth of cells with New Zealand sourced HyClone Characterized Fetal Bovine Serum.


Sourced in New Zealand with complete traceability back to the original source.

Low in antibodies and high in growth factors.

Produced using true pool technology for uniformity and consistency from bottle to bottle.

Filtered through three sequential 100 nm (0.1 µm) pore size-rated filters.

Virus panel testing according to 9 CFR 113.53.

HyClone Characterized Fetal Bovine Serum (FBS), New Zealand Origin is carefully collected, processed, and filtered in our own New Zealand facility. The great expanse of the Pacific ocean has protected New Zealand’s islands from many outside influences, both geographically and biologically. One of the benefits of this isolation is that New Zealand has the fewest reported bovine diseases in the world, making Characterized FBS, New Zealand Origin an excellent source of bovine serum as it offers greater security.


Characterized FBS is assayed for gamma globulin, alkaline phosphatase, lactate dehydrogenase, glutamic pyruvic transaminase, glutamic oxaloacetic transaminase, pH, total protein, albumin, blood urea nitrogen, creatinine, total bilirubin, sodium, potassium, calcium, chloride, inorganic phosphorus, osmolality, iron, total iron binding capacity (TIBC), percent iron saturation, glucose, and IgG. Included assays are subject to change without notice.


Additional treatments available including heat-inactivation and irradiation. Additional testing, including EMEA-conforming testing, is also available.


For decades, Cytiva's HyClone™ premium bovine serum products have exceeded industry standards for quality, purity, and regulatory compliance. HyClone™ serum processes are traceability certified by the International Serum Industry Association (ISIA) and, in addition, Cytiva has chosen to be an early adopter of scientific traceability by Oritain to prove the country of origin of their premium bovine serum products from the United States, Australia and New Zealand.

Fetal bovine serum (FBS) is a nutrient-rich cell culture supplement that is high in growth factors and low in antibodies, compared to non-fetal sera.


Characterized FBS for cell culture

HyCloneTM Characterized Fetal Bovine Serum (FBS) is an excellent alternative to more expensive defined sera, and meets the requirements of most discriminating FBS users. The final serum is assayed for provides important proteins, hormones, growth factors, metabolites, and nutrients for that support your healthy cell culture sprocess. Assay results are included in the certificate of analysis and biochemical assay list. Additional testing, including EMEA conformance testing, is also available.


Bacterial endotoxin-tested

Endotoxin contamination is a significant concern in research and manufacturing, especially when producing cell culture-derived products for use in humans or animals. The presence of endotoxin in cell cultures can also have adverse and unpredictable effects on cell growth, function, and phenotype that can compromise research results. Our patented closed-system blood collection method and rigorous quality control testing ensure that HyClone Characterized FBS meets industry standards of ≤ 25 EU/mL endotoxin. The final product also contains ≤ 25 mg/dL hemoglobin, which is an indicator of appropriate handling during collection and transport.


Virus-tested and quality-assured for reduced contamination risk

HyClone Characterized FBS is triple-filtered through serial 100 nm (0.10 μm) pore size-rated filters, which has become an industry standard for cell culture grade FBS. Before dispensing, each lot of serum is pooled using true pool technology to minimize variability from bottle to bottle.


The final serum is virus-tested according to 9 CFR 113.53 to demonstrate that there are no detectable levels of specified viruses, pathogenic agents, and hemadsorbing agents. Robust sterility testing further confirms that the final product contains no detectable growth of bacteria or fungi (current USP) and no detectable mycoplasma.


Post-filtration treatments for added process security

Gamma-irradiated and heat-inactivated FBS options are available to further reduce the risk of adventitious agents, particularly when manufacturing products for use in humans or animals. The irradiation process is validated to deliver a minimum dose of 25 kGy.
