【熒光標記人/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.
產品介紹:
牛血清白蛋白,英文名稱為BovineSerum Albumin,也稱Bovinealbumin,或CohnFraction V,簡稱BSA。BSA有著極其廣泛的實驗室應用,在免疫實驗中常用作封閉劑,包括ELISA、WB(Western Blot)。作為載體蛋白,將其交聯于半抗原和其他弱抗原可以使它們在抗體生產中具有更強的免疫原性。在限制性內切酶消化反應中,BSA常常被用作一些酶的反應穩定劑,并且能防止它粘附到管壁和槍頭上。BSA也常用于生物制藥的生產過程或者作為營養物用于細胞和微生物培養。除此之外,還作為蛋白定量檢測的標準品使用。我們提供的BSA產品,使用優質牛血漿,利用熱休克法(Heat Shock)法制備而成。
牛血清白蛋和人血清白蛋白在藥物靶向和藥物傳遞方面的介紹:
與正常組織相比,腫瘤組織的血管豐富,結構特殊 一個重要的表現就是血管內皮間隙較大,這種病變情況下大分子可以透過腫瘤組織血管壁的原因,然而在健康組織的血管中只有小分子可以通過這一內皮屏障,通常大分子藥物流體動力學半徑大于2nm小于10nm 人血清白蛋白的有效半徑是7.2nm 因此可以滲入腫瘤組織而不能進入正常組織。
在病例條件下 腫瘤細胞在生長或轉移時,病變細胞釋放的化學物質和腫瘤衍生物的甲狀腺激素相關肽均通過產生NO和激活KATP來降低集合淋巴管“節律泵”的活性,從而影響了淋巴的生成 轉運使得腫瘤組織淋巴回流較小,分子量相對較小的物質從腫瘤間質中清除較快,而大分子被截留,因此大分子物質還可以在腫瘤組織中選擇性的聚集。高血管通透性和截留率是白蛋白作為抗腫瘤藥物靶向載體的必要條件,白蛋白的這種效應符合大分子物質在腫瘤組織的透過性增強及滯留效應。
我公司可以提供各種白蛋白熒光探針和活化基團改性的牛血清白蛋白和人血清白蛋白產品,并且可以做一些白蛋白復合定制類產品。

【熒光標記和功能化卵清蛋白】
蛋清中的主要蛋白質包括卵清蛋白、卵轉鐵球蛋白、類卵沾蛋白、卵沾蛋白、溶菌酶、球蛋白G2、球蛋白G3等。卵清蛋白等電點4.5,其本質是含磷糖蛋白。卵清蛋白是蛋清中的主要蛋白組分,其結構與性質會顯著影響蛋清蛋白在食品加工過程中的功能性質。因此研究卵清蛋白在熱處理或美拉德反應后的變化對了解蛋清蛋白在食品加工過程中的結構與性質的變化有重要意義。
卵清蛋白是一種優質蛋白質,占蛋清蛋白總量的54%-69%,卵清蛋白是典型的球蛋白,分子量為44.5kDa,屬含磷糖蛋白,含有四個自由巰基、385個氨基酸殘基[1] 。這些氨基酸殘基相互纏繞折疊形成具有高度二級結構的球型結構,大部分為α-螺旋和β-折疊。卵清蛋白中心有1個二硫鍵和4個巰基,當加熱時暴露出來,通過分子間相互作用使卵清蛋白膠體結構變得更穩定

【乳清蛋白lactalbumin】
該納米載體取材綠色、設計巧妙,可在腫瘤部位依次針對腫瘤表面過表達酶、微酸和高谷胱甘肽(GSH)濃度等微環境實現三重響應性釋藥(圖2)。作者首先通過定向酶解奶酪副產物-乳清蛋白獲得兩親性多肽,在水溶液中可自組裝形成30納米單分散膠束peptosome(PS),高效荷載疏水性抗癌藥物姜黃素Cur,解決了姜黃素水溶液難溶的問題,并降低其對正常組織的副作用。隨后他們對其表面修飾功能肽段PePm,其中Pe可靶向乳腺癌表面的ErB2受體,且兼具較好的抗癌轉移效果。此外,Pm片段可以根據腫瘤表面過表達金屬基質蛋白酶MMP的特異性水解,通過交聯單個載體內部自身巰基形成二硫鍵,使PS具有癌細胞高GSH濃度響應釋藥的功能。他們將所構建的載體PePm/PS/Cur經尾靜脈注射到小鼠體內后,經EPR效應和Pe的靶向效應在腫瘤部位高度富集,載體表面Pe肽被MMP水解脫離,使Pe肽留在腫瘤細胞表面發揮抑瘤和抗轉移效果。PS/Cur繼續通過“質子海綿”效應從癌細胞溶酶體中逃逸,在細胞質內通過GSH響應逐漸解體,釋放出PS/Cur內荷載的姜黃素,發揮抑制腫瘤的作用。

【熒光標記刀豆求蛋白A】:
刀豆球蛋白A(Con A),又名刀豆凝集素、刀豆素,是一種植物血凝素,具有強力的促有絲分裂作用,有較好的促淋巴細胞轉化反應的作用,其促淋巴細胞轉化最適濃度為40-100μg/ml,能沉淀肝糖原,凝集羊、馬、狗、兔、豬、大鼠、小鼠、豚鼠等動物及人紅細胞。還能選擇性激活抑制性T細胞(Ts)細胞,對調節機體免疫反應具有重要作用。因此,通過使用Con A來活化病態(或老年)時的Ts細胞這一途徑,可望改觀一些自身免疫性疾病,甚或移植物排斥反應或惡性腫瘤的防治前景。
刀豆蛋白(ConcanavalinA,Con A)是從刀豆(Jack bean)中提取出來的凝集素,能沉淀多種糖類,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質等多種糖蛋白,還沉淀肺炎球菌多糖,并能凝集多種紅細胞。Con A 能和很多細菌和動物細胞反應,能區分某些正常和腫瘤細胞,能促進細胞分裂(促有絲分裂作用)。Con A IV 用于淋巴下撥轉化實驗,也被用來刺激T細胞產生IL-1 樣因子,還用于脾細胞增生,研究激活所必需的配體/受體作用。此外,尚區分正常分泌ACTH 的垂體細胞和分泌ACTH 的腺腫瘤細胞、用于研究糖基化在離子通道調節中的作用、用于糖蛋白的分離純化和多糖、糖蛋白糖鏈結構的研究等。
1992 年,Tiegs 等成功地應用刀豆蛋自A(ConA)誘發了小鼠特異性肝損傷,這一實驗模型是近年來新發展起來的由T 淋巴細胞介導的肝損害,它的建立和應用為深入研究肝細胞損害的細胞學與分子學機制以及進行治療藥物篩選提供了更為方便和理想的實驗動物模型。
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.

產品介紹:
天然蛋白A(Protein A)是一種發現于金黃色葡萄球菌的細胞壁表面蛋白,天然蛋白G(Protein G)是一種分離自G型或C型鏈球菌屬的細胞表面蛋白,二者功能相似,主要通過與免疫球蛋白(Ig)的Fc區相互作用,可結合大多數哺乳動物的IgG。然而兩者結合特異性上有所不同(詳細見附錄1,蛋白A,G對不同物種Ig的結合能力總表),如蛋白G對人IgG3,大鼠IgG2a,綿羊IgG1具有很高的親和力,但蛋白A對這些Ig結合力很弱。蛋白A,蛋白G常共價偶聯在固體載體如瓊脂糖珠或丙烯酸樹脂小珠上,直接用以做免疫沉淀(IP)或者免疫共沉淀(Co-IP)來進行蛋白功能相關研究,或者直接裝在層析柱上來純化單克隆或者多克隆抗體。
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,不僅維持其本身的Ig親和特性,同時也去除了天然蛋白本身的非主要結合域以降低非特異性結合。本品是同時共價偶聯了蛋白A和蛋白G的瓊脂糖珠,比單獨的蛋白A或者蛋白G都有更廣的結合范圍,適合于所有蛋白A瓊脂糖珠和蛋白G瓊脂糖珠單獨可以結合的Ig,實用性更高。本品為50%的懸液,1 ml Protein A/G 瓊脂糖珠可結合約25 mg人IgG。
