RecombinantMurine Sonic HedgeHog (SHH)rMuSHHHhg1Hxl3
Members of the Hedgehog (Hh) family are highly conserved proteins that are widely represented throughout the animal kingdom. The three known mammalian Hh proteins, Sonic (Shh), Desert (Dhh) and Indian (Ihh), are structurally related and share a high degree of amino acid sequence identity. Each Hh protein has a unique expression pattern and distinct biological role within its respective region of secretion. All Hh proteins use the same signaling pathway and can substitute for each other in experimental systems. Shh has been found to have a critical role in development, acting as a morphogen in the patterning of limbs, brain structure, facial structure, lungs, spinal cord, thalamus and the teeth. Shh has been shown to attract commissural axons in the developing spinal cord by attracting or repelling retinal ganglion cell (RGC) axons depending on concentration. Murine SHH is frequently coexpressed with BMP2, BMP4, and BMP6.

GoldBio活体成像技术:早在1999年由美国哈佛大学Weissleder博士率先提出了分子影像学(molecularimaging,MI)的概念,即应用影像学的方法对活体状态下的生物过程进行细胞和分子水平的定性和定量研究。活体成像便是基于分子影像学孕育而生的,通过这个成像系统,可以观测活体动物体内肿瘤的生长及转移,感染性疾病的发展进程,特定基因的表达等生物学过程。活体成像技术主要采用生物发光(bioluminescence)与荧光(fluorescence)两种技术。★生物发光是用荧光素酶基因标记细胞或DNA。★荧光技术则采用荧光报告基团(GFP、RFP,Cyt及dyes等)进行标记。★这一技术对肿瘤微小转移灶的检测灵敏度极高,不涉及放射性物质和方法,非常安全。操作极其简单、所得结果直观、灵敏度高。
活体成像两种检测技术介绍活体成像特点优点缺点生物发光检测bioluminescence★荧光素酶(Luciferase)对基因、细胞和活体动物进行标记;★荧光素酶催化底物(例如荧光素钾盐)反应后,会产生化学发光。这种光是由化学反应而来,不需要激发光;★标记方法是通过克隆技术,将荧光素酶的基因插入到预期观察的细胞染色体内,通过对克隆细胞进行筛选,培养出能稳定表达荧光素酶的细胞株。再将细胞株转移至特定的小鼠体内形成模型。★特异性强,无自发荧光;★高灵敏度,在体内可检测到几百个细胞,检测的深度在3-100px;★定量精确 ★信号较弱,检测时间较长;★仪器精密度要求较高;★细胞或基因需要转基因标记;★不可用于人体,不适用于抗体、多肽等标记荧光检测fluorescence★采用荧光报告基因(GFP、RFP等)或荧光染料进行标记;★需要外接激发光源,利用报告基因、荧光蛋白质或染料产生的荧光,就可以形成体内的生物光源。★荧光染料、蛋白标记能力强;★信号强,成像速度快,操作简便,实验成本较低;★未来可用于人;★适用范围广,可以是动物、细胞、微生物,也可以是抗体、药物、纳米材料等。★存在自发荧光,影响灵敏度;★光容易被动物组织吸收;★检测深度受限;★背景光干扰,定量准确度低

各位业内前辈,我们正在考虑引进符合GMP认证标准的CHO细胞系,用于表达可做疫苗生产的重组蛋白类。目前已有符合标准信息的是Thermofisher的CHO-S悬浮培养细胞资料,希望能再多了解一些和这株细胞类似的其他公司符合GMP标准的生产株细胞做个比较。谢谢指教!

生物合成人胰岛素注射液,比如诺和灵R笔芯。是单一品种、不是混合的胰岛素。是不含鱼精蛋白的短效胰岛素。
