Ubiquitin chains vary in length, linkage, and function. K33-linked Tri-Ubiquitin Chains (Ub3) are ideal for investigating Ubiquitin-binding proteins and as substrates for Ubiquitin-specific isopeptidases. Reaction conditions will need to be optimized for each specific application. IMPORTANT: Heating this product in SDS-PAGE buffer or terminating reactions containing this product with heated SDS-PAGE buffer could lead to unexpected, high apparent molecular weight banding or smearing on gels that is not representative of product purity. For optimal results, we recommend incubation in SDS-PAGE buffer + DTT at <40 °c="" for="" 20="" minutes="" prior="" to="" gel="" electrophoresis.="">40>
Product Datasheets
Carrier Free
CF stands for Carrier Free (CF). We typically add Bovine Serum Albumin (BSA) as a carrier protein to our recombinant proteins.Adding a carrier protein enhances protein stability, increases shelf-life, and allows the recombinant protein to be stored at a more dilute concentration.The carrier free version does not contain BSA.
In general, we advise purchasing the recombinant protein with BSA for use in cell or tissue culture, or as an ELISA standard.In contrast, the carrier free protein is recommended for applications, in which the presence of BSA could interfere.

Background: Tri-Ubiquitin
Linkage specific Poly-Ubiquitin chains may be used as a substrate for in vitro reactions with deubiquitinating enzymes ("DUB"s") that cleave the peptide or isopeptide linkage between adjacent Ubiquitin molecules. Poly-Ubiquitin chains can also be used to investigate mechanisms of binding and recognition between the chains and other proteins that contain Ubiquitin-Associated domains (UBAs), Ubiquitin-interacting motifs (UIMs), ZnF"s and/or other Ubiquitin-sensing elements.
K33-linked Tri-Ubiquitin chains are manufactured using recombinant Ubiquitin and purely enzymatic techniques to avoid the potential for contaminating synthetic intermediates. The correctness of linkage and purity of each production lot is assessed using the Absolute Quantitation of Ubiquitin method (Ub-AQUA), an LCMS-based technique that provides extremely accurate information on the composition of Poly-Ubiquitin samples.

前段时间用了一下振动切片机,感觉要想准确的切出海马切片不太容易。然后搜索了一下,发现国外用McIlwaintissuechopper这种切片机的人也挺多的,而国内很多都是用的振动切片机。先上两张图
McIlwaintissuechopper
这种切片机的特点是从上向下竖直切下来,每切一次,下面的盘子移动一点点
振动切片机
这种切片机是水平切,将脑组织用502粘在那个小台子上切
两种切片机,我个人的理解是,上面那种可能要更好一点,对于振动切片机,组织块用502粘在小台子上,如果组织块比较大,下面一点点组织浪费也不要紧。但是如果我想切海马,先把海马剥离出来,然后再粘贴在振动切片机上,这样就没办法切了,海马体是个细长的结构,粘上去基本上就全浪费了(我看到很多国内文献都是用的振动切片机,先分离出海马体,然后再切,不知道他们是怎么解决这个问题的,在我看来,1到2周的乳大鼠,分离出的海马体是非常小的,再用胶水粘在小台子上,那都没得切了,不要告诉我说少涂掉胶水,这也解决不了根本问题)但是如果我平放在上面的组织切片机上,从上向下切,这样就没事,可以切出很多切片,完全不会浪费,但还是有个问题,上面那种切片机,虽然每切一次,下面的盘子移动一点距离,但脑组织毕竟是非常柔软的,会不会因为太柔软而不能切的均匀?放在冰水混合物中冻硬一点能不能解决这个问题?
家用的菜刀也叫切片机,工业用的医院切组织用的也叫切片机。
1:德国美康冰冻切片机:
德国美康HM550型冰冻切片机,使用双半导体致冷技术,切片机箱体制冷-35℃,快速制冷架一次可放12个样品,其中4个位点可降温至-60℃,样品头制冷可达-50℃。采用步进马达进样技术,切片厚度精度稳定,切片厚度范围:1-500微米。切片厚度的调整位于冷冻箱体之外便于操作。具有样品头位置记忆功能,切片计数功能,全自动化程序除霜功能,切片回缩功能,完全满足日常冰冻切片快速,精确,安全的需要。
2:徕卡切片机:
准确的诊断有赖于精确的切片。精确的切片依靠正确类型的切片机。徕卡开创了切片术的历史,不断提供各种系列的切片机,为各项应用供应高质量的切片。选择适用于您标本类型的徕卡切片机,树立诊断信心,给予患者更可信赖的保障。
3:切片机类型:

2、装机功率:MB达到50-85KW; MB135KW,而HTC虽然也是75KW,但是将砂浆泵的功率设为0.75KW,根据这一要求,更是将其使用辅料的范围直接限定成了只能用日本的切割液,并且是用日本的“619”配方的硅片切割液,对用户来说带来了很大的麻烦。由于HTC的装机功率极其的小,如果用国内的太阳能硅片切割液,就会因为液的粘度太大,无法协调硅片切割液和碳化硅微粉的配比比例和砂浆粘度的问题,除非切割液厂家为其专供。
3、对切割原料的要求:
MB等机器,要求硅片切割液和碳化硅微粉的配比比例一般控制在1:0.92-0.95,砂浆密度在1.630-1.635就可以切的相当理想。即便出现配比比例更大,甚至砂浆密度达到1.67左右都照样不会有什么问题,只要砂浆粘度控制在200--250就可以。但是HTC要求砂浆密度不能高于1.57,就是说只能控制在1.55-1.57.砂浆粘度在150左右,这样国内的硅片切割液液就会出现砂浆密度配在1.57,可能砂浆粘度还不到120,而如果把砂浆粘度调到150,密度就超过了1.57,甚至超过了1.60。砂浆粘度过大,直接的说法是会导致机器报警,其实更深层次的影响还有可能会导致片子洗不干净,出现灼伤片,或者电机发热,对机器本身的轴承有很大的磨损。
切片机是切制薄而均匀组织片的机械,组织用坚硬的石蜡或其他物质支持,每切一次借切片厚度器自动向前(向刀的方向)推进所需距离,厚度器的梯度通常为1微米。切制石蜡包埋的组织时,由于与前一张切片的蜡边粘着,而制成多张切片的切片条。
