什么是牛血清白蛋白？
牛血清白蛋白（BSA）是一种球状蛋白（66,000 Da分子量），由于其稳定性和对生物反应的干扰而被广泛用于许多生化应用中。
牛血清白蛋白（BSA）结构：
BSA是一条单条多肽链，由约583个氨基酸残基组成，不含碳水化合物。在pH 5-7时，它包含17个链内二硫键和1个巯基。
牛白蛋白的物理性质和应用：
BIOFOUNT的各种牛血清白蛋白，纯度范围为95-99％之间。我们生产和分销多种主要方法纯化的牛血清白蛋白，包括真正的Cohn分馏方法，改良的乙醇分馏方法，热休克和色谱法。
※ BSA产品可用作阻滞剂，稀释剂，稳定剂和蛋白质标准品。
※ 在许多行业领先的诊断测定中用作关键成分。

标准等级BSA：
※ 不含IgG，几乎不含污染的酶，盐，重金属和低分子量污染物
※ 出色的溶解性，即使在高浓度下也具有出色的透明度，可过滤性和低紫外线背景
※ 内毒素极低，生物负荷低，在培养基中高度溶解-兽医和生物技术应用的重要特征
※ 标准等级BSA
※ 标准级BSA产品在兽医的监督下对动物进行了事前检查和事后检查，并使其无传染性或传染性疾病以及有害寄生虫的通过。
试剂级BSA：
※ 试剂级BSA的收集遵循与标准级BSA相同的指导原则；但是，该产品需要进一步加工以生产高纯度粉末。加工过程可能包括广泛的膜透析和过滤，包括木炭过滤。这种额外的处理有助于最大程度地减少分析物，包括可能在敏感的体外诊断测定中引起背景干扰以及对敏感的细胞和微生物培养系统产生抑制作用的非酯化脂肪酸。试剂级BSA中的纯度达到或超过98％。
仅供研究使用。不用于诊断过程。

不同等级的牛血清白蛋白的应用及说明：
Standard grade and reagent grade BSA products from SeraCare offer IVD manufacturers a consistent, reliable source of material for immunoassay, protein chemistry, and cell culture applications.
IgG-free, and virtually free of contaminating enzymes, salts, heavy metals, and low molecular weight contaminants
Outstanding solubility with excellent clarity, filterability, and low UV background, even at high concentrations
Very low in endotoxin, with low bioburden, and highly soluble in media - important characteristics for veterinary and biotechnology applications
Standard Grade BSA
Standard grade BSA product is derived from bovine plasma collected at USDA?licensed facilities in the United States. Animals received ante?mortem and post mortem inspection under veterinary supervision and were passed as free of infectious or contagious diseases and injurious parasites.
Reagent Grade BSA
Reagent grade BSA is collected under the same guidelines as standard grade BSA; however, this product undergoes further processing to produce a highly purified powder. Processing may include extensive membrane dialysis and filtration, including charcoal filtration. This additional processing helps to minimize analytes, including non?esterified fatty acids that can cause background interference in sensitive in vitro diagnostic assays, as well as inhibition in sensitive cell and microbial culture systems. Purity levels in reagent grade BSA meet or exceed 98%.
For research use only. Not for use in diagnostic procedures.

1.High azithromycin concentration in lungs by way of bovine serum albumin microspheres as targeted drug delivery: lung targeting efficiency in albino mice.
Ramaiah B1, Nagaraja SH2, Kapanigowda UG3, Boggarapu PR3, Subramanian R4. Daru. 2016 May 5;24(1):14. doi: 10.1186/s40199-016-0153-x.
BACKGROUND: Following administration, the antibiotic travels freely through the body and also accumulates in other parts apart from the infection site. High dosage and repeated ingestion of antibiotics in the treatment of pneumonia leads to undesirable effects and inappropriate disposition of the drug. By way of targeted lung delivery, this study was intended to eliminate inappropriate azithromycin disposition and to achieve higher azithromycin concentration to treat deeper airway infections.
2.Light Scattering Analysis of Mono- and Multi-PEGylated Bovine Serum Albumin in Solution: Role of Composition on Structure and Interactions.
Ferebee R, Hakem IF, Koch AH, Chen M, Wu Y, Loh D, Wilson DC, Poole JL, Walker JP, Fytas G, Bockstaller MR. J Phys Chem B. 2016 May 5. [Epub ahead of print]
The effect of polymer conjugation on the interactions between proteins in solution is evaluated by systematic analysis of the second virial coefficient (A2) for the particular example of single- and double-PEGylated bovine serum albumin (PEG-BSA) in dilute PBS solution. The effect of PEGylation on A2 is found to sensitively depend on both the composition and the distribution of PEG segments within the conjugate. Most importantly, at a given PEG volume fraction, A2 significantly increases with the degree of polymerization of tethered chains. Hence, a lesser number of long chains is more effective in solubilizing BSA than a correspondingly larger number of short chains. Analysis of the hydrodynamic radii of protein-PEG conjugates suggests that the increased solubility is concurrent with a structural transition in the case of high molecular PEG grafts that results in compact core-shell-type structures. The results reveal a link between the composition, structure, and solubility of polymer-conjugates that might benefit the understanding of their biochemical characteristics and their design for functional material applications.
