血清白蛋白是人血浆中发现的丰富的蛋白质,它在维持渗透压和血液pH方面起着至关重要的作用。白蛋白在多种配体的运输,分配和代谢中也起着重要作用,包括当今市场上许多重要的药物。它实际上是大自然母亲的给药系统。药物亲和力和与白蛋白的结合位置可显着改变药物的半衰期,分布和代谢,从而在许多重要药物的ADME(吸收,分布,代谢和分泌)中起主要作用。

由于白蛋白的丰度,纯度和特殊性质,如化学结合和稳定作用,它已被成功地用于许多应用中。

一些常见的应用:

 

  • 血容量扩张剂(主要是非重组的)。白蛋白的主要药物应用,代表了一个数十亿美元的产业,汇集了过时的人类血液。

 

  • 生物制剂:治疗性加合物/制剂,用于改善血液循环半衰期

 

  • 生物制剂:用于生物疗法和疫苗的辅料配方

 

  • 细胞培养:原代细胞扩增; 改进的CHO细胞培养导致药物抗体产生。

 

  • 医疗器械:Invitro受精; 医疗器械涂料

 

  • 生物材料的发展

 

  • 冷冻保存

 

  • 用于药物研究和开发的药物结合相互作用的结构和溶液研究

产品描述

牛血清白蛋白,英文名称为Bovine Serum Albumin,也称Bovine albumin,或Cohn Fraction V,简称BSA。BSA有着极其广泛的实验室应用,在免疫实验中常用作封闭剂,包括ELISA、WB(Western Blot)。作为载体蛋白,将其交联于半抗原和其他弱抗原可以使它们在抗体生产中具有更强的免疫原性。在限制性内切酶消化反应中,BSA常常被用作一些酶的反应稳定剂,并且能防止它粘附到管壁和枪头上。BSA也常用于生物制药的生产过程或者作为营养物用于细胞和微生物培养。除此之外,还作为蛋白定量检测的标准品使用。我们提供的BSA产品,使用优质牛血浆,利用热休克法(Heat Shock)法制备而成。

牛血清白蛋白,标准级别(BSA, Standard Grade)可以满足大部分常规实验需求,如用作免疫封闭剂、组织细胞(微生物动物及昆虫细胞等)培养养料和培养成分、蛋白/酶稳定剂以及蛋白定量标准品。

产品描述

牛血清白蛋白,英文名称为Bovine Serum Albumin,也称Bovine albumin,或Cohn Fraction V,简称BSA。BSA有着极其广泛的实验室应用,在免疫实验中常用作封闭剂,包括ELISA、WB(Western Blot)。作为载体蛋白,将其交联于半抗原和其他弱抗原可以使它们在抗体生产中具有更强的免疫原性。在限制性内切酶消化反应中,BSA常常被用作一些酶的反应稳定剂,并且能防止它粘附到管壁和枪头上。BSA也常用于生物制药的生产过程或者作为营养物用于细胞和微生物培养。除此之外,还作为蛋白定量检测的标准品使用。我们提供的BSA产品,使用优质牛血浆,利用热休克法(Heat Shock)法制备而成。

牛血清白蛋白,标准级别(BSA, Standard Grade)可以满足大部分常规实验需求,如用作免疫封闭剂、组织细胞(微生物动物及昆虫细胞等)培养养料和培养成分、蛋白/酶稳定剂以及蛋白定量标准品。

产品描述

牛血清白蛋白,英文名称为Bovine Serum Albumin,也称Bovine albumin,或Cohn Fraction V,简称BSA。BSA有着极其广泛的实验室应用,在免疫实验中常用作封闭剂,包括ELISA、WB(Western Blot)。作为载体蛋白,将其交联于半抗原和其他弱抗原可以使它们在抗体生产中具有更强的免疫原性。在限制性内切酶消化反应中,BSA常常被用作一些酶的反应稳定剂,并且能防止它粘附到管壁和枪头上。BSA也常用于生物制药的生产过程或者作为营养物用于细胞和微生物培养。除此之外,还作为蛋白定量检测的标准品使用。我们提供的BSA产品,使用优质牛血浆,利用热休克法(Heat Shock)法制备而成。

牛血清白蛋白,低内毒素(BSA, Low Endotoxin)产品中内毒素含量低于2.0 EU/mg,在内毒素水平敏感的细胞培养中,该产品可作为天然载体蛋白使用;适用于无血清或化学成分限定的细胞和组织培养中;有效的稳定和稀释敏感蛋白溶液;也可用于ELISA等诊断检测。

产品描述

牛血清白蛋白,英文名称为Bovine Serum Albumin,也称Bovine albumin,或Cohn Fraction V,简称BSA。BSA有着极其广泛的实验室应用,在免疫实验中常用作封闭剂,包括ELISA、WB(Western Blot)。作为载体蛋白,将其交联于半抗原和其他弱抗原可以使它们在抗体生产中具有更强的免疫原性。在限制性内切酶消化反应中,BSA常常被用作一些酶的反应稳定剂,并且能防止它粘附到管壁和枪头上。BSA也常用于生物制药的生产过程或者作为营养物用于细胞和微生物培养。除此之外,还作为蛋白定量检测的标准品使用。我们提供的BSA产品,使用优质牛血浆,利用热休克法(Heat Shock)法制备而成。

本品为无脂肪酸的牛血清白蛋白(Fatty Acid Free BSA),其内的脂肪酸含量非常低(0.02%),几乎可忽略,且易溶解。通常用作微量元素,脂肪酸,激素和生长因子的载体蛋白,加入无血清培养体系。本品允许BSA内加入某些特定的脂肪酸以促进细胞生长。适用于避免脂类或脂肪酸干扰结果的激素或胆固醇分析检测。每批产品中总脂肪酸含量≤0.02%。【注:本产品脂肪酸含量低于Sigma的同类产品A8806,且白蛋白含量高出三个百分点,达到99%,但价格仅为其20%。】目前使用本公司提供的无脂肪酸牛血清白蛋白用户已经达到200个实验室以上。

除了无脂肪酸的BSA,我司还提供其他应用级别的BSA,包括诊断级(Cat: 36102ES25),标准级(Cat: 36101ES25),低内毒素(Cat: 36106ES25),无蛋白酶(Cat: 36105ES25)以及无DNase、蛋白酶、IgG级别(Cat: 36103ES25)。

EMCARE牛血清白蛋白的优点


 

CPbio Reproduction为胚胎移植市场制造了一整套适合胚胎的培养基。我们的EMCARE™产品线包括用于冲洗,搬运,冷冻和解冻动物胚胎的产品。的MOPS缓冲液(惰性两性离子)提供稳定的微环境。新西兰来源的牛血清白蛋白在*冲洗和处理介质中提供天然和保护性表面活性剂和能源。当不需要牛白蛋白时,EMCARE™BioFree冲洗液和EMCARE™冲洗液是可选的。

专为胚胎移植行业的专业兽医和动物繁殖研究人员设计,EMCARE™培养基为冲洗,处理,冷冻和解冻胚胎提供了理想的条件。

 

EMCARE™牛血清白蛋白

ICPbio的牛血清白蛋白进行色谱分级分离,导致白蛋白结构变性小。意即:

  • 更多可用的结合位点来保护胚胎
  • 不含其他血清成分和结合污染物
  • 内毒素水平很低

当在无蛋白质培养基中培养胚胎时测量到生化结果。其中一些变化是:

  • 与在白蛋白存在下培养的那些相比,减少了氧气消耗(已公布)。
  • 与在白蛋白存在下培养的那些相比,通过TCA循环的通量增加了丙酮酸盐摄取,但是减少(公开)。
  • 与在白蛋白存在下培养的那些相比,蛋白质含量降低,并且体内对照表明蛋白质降解和蛋白质合成比例变化(已公布)。
  • 已经在含有BSA或PVA的培养基中分析了植入前的牛胚胎中的基因表达模式。发现包括培养基组成和氧气张力的基本培养体系对特定转录物的量具有深远影响,而蛋白质来源仅具有弱作用。

 

EMCARE™胚胎移植产品

  • EMCARE™Complete Ultra Flushing Media含有ICPbio低内毒素牛血清白蛋白,可提供表面活性剂和胚胎保护特性,并具有吸收增塑剂,内毒素和蛋白酶的结合位点。
  • 低泡沫配方 – 比以前的配方少50%的泡沫。

含有0.4%的ICPbio牛血清白蛋白

 

EMCARE™是理想的媒体:

安全:

  • MOPS缓冲液比旧商用缓冲液提供更稳定的微环境
  • 天然的新西兰源辐照白蛋白清洁,保护并为胚胎提供能量
  • 无菌过滤
  • 受到广泛的质量保证程序

方便和可靠:

  • 准备就绪 – 采用现场准备的方便包装选项进行包装
  • 易于使用 – 冲洗组件连接
  • 不需要额外的过滤
  • 含有抗生素
  • 水质和离子强度可控制到严格的标准

专为胚胎移植(ET)行业的专业兽医和动物繁殖研究人员设计,EMCARE™培养基为冲洗,处理,冻结和解冻胚胎提供了理想的条件。

其优化的营养组合物增强了胚胎发育,并且MOPS缓冲液(惰性两性离子)提供更稳定的微环境。这是因为MOPS缓冲介质的毒性低于HEPES或磷酸盐介质。试验表明,MOPS缓冲培养基中的胚胎将比HEPES或磷酸盐缓冲培养基中的胚胎多出近20%。

EMCARE™预混合即用型介质可节省时间并保证一致的质量。

对于天然的保护性表面活性剂和能量来源,冲洗和处理介质还包含新西兰来源的ICPbio牛血清白蛋白。这是病毒筛选和照射到2.5Mrads,以确保安全,天然的胚胎保护剂。

所有产品含有25mg / L硫酸卡那霉素抗生素。
