进口胎牛血清,射线照射

Product Name: Fetal Bovine Serum (FBS), US Origin, Gamma-irradiated.进口胎牛血清,射线照射

Product description: Product OverviewGamma irradiation is a process which involves exposing material to high energy gamma photons released by radioisotopes, such as cobalt 60. This energy is transferred from the photons to the products, and is responsible for organism inactivation by ionization of nucleic acid bonds. The irradiation of serum is intended to provide complete assurance of viral inactivation.

Isotype: Cocktail.

Host Species: Alligator.

Purification: Affinity purified.

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.

光电材料|光电效应对x射线密度测井的影响及校正

为了提高x射线密度测量的精度,研究了光电效应对x射线密度测井的影响。


首先,根据地层x射线衰减原理,利用XCOM程序,分析了地层x射线康普顿散射和光电效应的变化规律;


其次,在此基础上研究了光电效应对x射线密度测井的影响。


第三,提出了利用岩性窗口和密度窗口计数计算地层体积密度来校正光电效应的方法。


最后,通过MCNP仿真验证了该方法的有效性。


结果表明,光电效应是影响x射线密度测量精度的重要因素,x射线能量越低,光电效应对x射线密度测量的影响越大,密度测量精度越低。


由于Cs-137源释放的γ射线处于高能级,利用密度窗计数计算地层体积密度时,光电效应的影响基本可以忽略不计;相反,x射线源释放的x射线处于低能级,用x射线测量地层体积密度时,不能忽略光电效应的影响。


地层体积密度计算方法能有效消除光电效应的影响,测量精度达到0.01g/cm3左右,为x射线密度测井过程中准确测量密度提供了理论基础。
