【荧光标记人/牛血清白蛋白】:
Bovine serum albumin (BSA) is a slightlyacidic ~66 kd protein. BSA is commonly used in biological research due to itslow cost and inertness. Dilute enzymes can be stabilized by BSA (useful forrestriction digests). BSA is a common blocking agent in western blotting andELISA’s. Although, bovine serum albumin is exceptionally soluble (up to 50% w/vin buffered saline), it is typically used at a concentration of 0.1-1% w/v.
产品介绍:
牛血清白蛋白,英文名称为BovineSerum Albumin,也称Bovinealbumin,或CohnFraction 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。
牛血清白蛋和人血清白蛋白在药物靶向和药物传递方面的介绍:
与正常组织相比,肿瘤组织的血管丰富,结构特殊 一个重要的表现就是血管内皮间隙较大,这种病变情况下大分子可以透过肿瘤组织血管壁的原因,然而在健康组织的血管中只有小分子可以通过这一内皮屏障,通常大分子药物流体动力学半径大于2nm小于10nm 人血清白蛋白的有效半径是7.2nm 因此可以渗入肿瘤组织而不能进入正常组织。
在病例条件下 肿瘤细胞在生长或转移时,病变细胞释放的化学物质和肿瘤衍生物的甲状腺激素相关肽均通过产生NO和激活KATP来降低集合淋巴管“节律泵”的活性,从而影响了淋巴的生成 转运使得肿瘤组织淋巴回流较小,分子量相对较小的物质从肿瘤间质中清除较快,而大分子被截留,因此大分子物质还可以在肿瘤组织中选择性的聚集。高血管通透性和截留率是白蛋白作为抗肿瘤药物靶向载体的必要条件,白蛋白的这种效应符合大分子物质在肿瘤组织的透过性增强及滞留效应。
我公司可以提供各种白蛋白荧光探针和活化基团改性的牛血清白蛋白和人血清白蛋白产品,并且可以做一些白蛋白复合定制类产品。

蛋清中的主要蛋白质包括卵清蛋白、卵转铁球蛋白、类卵沾蛋白、卵沾蛋白、溶菌酶、球蛋白G2、球蛋白G3等。卵清蛋白等电点4.5,其本质是含磷糖蛋白。卵清蛋白是蛋清中的主要蛋白组分,其结构与性质会显著影响蛋清蛋白在食品加工过程中的功能性质。因此研究卵清蛋白在热处理或美拉德反应后的变化对了解蛋清蛋白在食品加工过程中的结构与性质的变化有重要意义。
卵清蛋白是一种优质蛋白质,占蛋清蛋白总量的54%-69%,卵清蛋白是典型的球蛋白,分子量为44.5kDa,属含磷糖蛋白,含有四个自由巯基、385个氨基酸残基[1] 。这些氨基酸残基相互缠绕折叠形成具有高度二级结构的球型结构,大部分为α-螺旋和β-折叠。卵清蛋白中心有1个二硫键和4个巯基,当加热时暴露出来,通过分子间相互作用使卵清蛋白胶体结构变得更稳定

【乳清蛋白lactalbumin】
该纳米载体取材绿色、设计巧妙,可在肿瘤部位依次针对肿瘤表面过表达酶、微酸和高谷胱甘肽(GSH)浓度等微环境实现三重响应性释药(图2)。作者首先通过定向酶解奶酪副产物-乳清蛋白获得两亲性多肽,在水溶液中可自组装形成30纳米单分散胶束peptosome(PS),高效荷载疏水性抗癌药物姜黄素Cur,解决了姜黄素水溶液难溶的问题,并降低其对正常组织的副作用。随后他们对其表面修饰功能肽段PePm,其中Pe可靶向乳腺癌表面的ErB2受体,且兼具较好的抗癌转移效果。此外,Pm片段可以根据肿瘤表面过表达金属基质蛋白酶MMP的特异性水解,通过交联单个载体内部自身巯基形成二硫键,使PS具有癌细胞高GSH浓度响应释药的功能。他们将所构建的载体PePm/PS/Cur经尾静脉注射到小鼠体内后,经EPR效应和Pe的靶向效应在肿瘤部位高度富集,载体表面Pe肽被MMP水解脱离,使Pe肽留在肿瘤细胞表面发挥抑瘤和抗转移效果。PS/Cur继续通过“质子海绵”效应从癌细胞溶酶体中逃逸,在细胞质内通过GSH响应逐渐解体,释放出PS/Cur内荷载的姜黄素,发挥抑制肿瘤的作用。

【荧光标记刀豆求蛋白A】:
刀豆球蛋白A(Con A),又名刀豆凝集素、刀豆素,是一种植物血凝素,具有强力的促有丝分裂作用,有较好的促淋巴细胞转化反应的作用,其促淋巴细胞转化最适浓度为40-100μg/ml,能沉淀肝糖原,凝集羊、马、狗、兔、猪、大鼠、小鼠、豚鼠等动物及人红细胞。还能选择性激活抑制性T细胞(Ts)细胞,对调节机体免疫反应具有重要作用。因此,通过使用Con A来活化病态(或老年)时的Ts细胞这一途径,可望改观一些自身免疫性疾病,甚或移植物排斥反应或恶性肿瘤的防治前景。
刀豆蛋白(ConcanavalinA,Con A)是从刀豆(Jack bean)中提取出来的凝集素,能沉淀多种糖类,葡聚糖和果聚糖等很多其它多糖,以及免疫球蛋白和血型物质等多种糖蛋白,还沉淀肺炎球菌多糖,并能凝集多种红细胞。Con A 能和很多细菌和动物细胞反应,能区分某些正常和肿瘤细胞,能促进细胞分裂(促有丝分裂作用)。Con A IV 用于淋巴下拨转化实验,也被用来刺激T细胞产生IL-1 样因子,还用于脾细胞增生,研究激活所必需的配体/受体作用。此外,尚区分正常分泌ACTH 的垂体细胞和分泌ACTH 的腺肿瘤细胞、用于研究糖基化在离子通道调节中的作用、用于糖蛋白的分离纯化和多糖、糖蛋白糖链结构的研究等。
1992 年,Tiegs 等成功地应用刀豆蛋自A(ConA)诱发了小鼠特异性肝损伤,这一实验模型是近年来新发展起来的由T 淋巴细胞介导的肝损害,它的建立和应用为深入研究肝细胞损害的细胞学与分子学机制以及进行治疗药物筛选提供了更为方便和理想的实验动物模型。
Concanavalin A (con A) is a homotetrameric,26 kDa lectin derived from the jack bean, Canavalia ensiformis. Concanavalin Abinds to alpha-D glucose and alpha-D-mannose containing saccharides.Concanavalin A requires both Mn2+ and Ca2+ ions as a co-factor for binding.Since each con A has four binding sites, it can agglutinate cells such as redblood cells. Con A can also cause cell surface receptor aggregation which canbe mitogenic for some lymphocytes.

产品介绍:
天然蛋白A(Protein A)是一种发现于金黄色葡萄球菌的细胞壁表面蛋白,天然蛋白G(Protein G)是一种分离自G型或C型链球菌属的细胞表面蛋白,二者功能相似,主要通过与免疫球蛋白(Ig)的Fc区相互作用,可结合大多数哺乳动物的IgG。然而两者结合特异性上有所不同(详细见附录1,蛋白A,G对不同物种Ig的结合能力总表),如蛋白G对人IgG3,大鼠IgG2a,绵羊IgG1具有很高的亲和力,但蛋白A对这些Ig结合力很弱。蛋白A,蛋白G常共价偶联在固体载体如琼脂糖珠或丙烯酸树脂小珠上,直接用以做免疫沉淀(IP)或者免疫共沉淀(Co-IP)来进行蛋白功能相关研究,或者直接装在层析柱上来纯化单克隆或者多克隆抗体。
西安瑞禧生物科技有限公司使用的是基因改造后的蛋白A和蛋白G,不仅维持其本身的Ig亲和特性,同时也去除了天然蛋白本身的非主要结合域以降低非特异性结合。本品是同时共价偶联了蛋白A和蛋白G的琼脂糖珠,比单独的蛋白A或者蛋白G都有更广的结合范围,适合于所有蛋白A琼脂糖珠和蛋白G琼脂糖珠单独可以结合的Ig,实用性更高。本品为50%的悬液,1 ml Protein A/G 琼脂糖珠可结合约25 mg人IgG。
