Recombinant Human SUMO1 Protein, CF Summary
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: SUMO1
Human Small Ubiquitin-like Modifier 1 (SUMO1), also known as Sentrin, UBL1, and SMT3C, is synthesized as a 101 amino acid (aa) propeptide with a predicted molecular weight of 11.5 kDa. Human SUMO1 is the most unique of the four identified SUMO proteins and shares only 44%, 47%, and 41% aa sequence identity with SUMO2, SUMO3, and SUMO4, respectively. In contrast, human SUMO1 shares 100% aa sequence identity with the mouse ortholog. SUMOs are a family of small, related proteins that can be enzymatically attached to a target protein by a post-translational modification process termed SUMOylation (1-3). All SUMO proteins share a conserved Ubiquitin domain and a C-terminal diglycine cleavage/attachment site. Following cleavage of a four aa C-terminal prosegment, the C-terminal glycine residue of SUMO1 is enzymatically attached to a lysine residue on a target protein. In humans, SUMO1 is conjugated to a variety of molecules in the presence of the SAE1/UBA2 SUMO-activating (E1) enzyme and the UBE2I/Ubc9 SUMO-conjugating (E2) enzyme (4,5). In yeast, the SUMO-activating (E1) enzyme is Aos1/Uba2p (6). SUMOylation can occur without the requirement of a specific SUMO ligase (E3), where SUMO1 is transferred directly from UBE2I/Ubc9 to specific substrates. In Alzheimer"s disease models SUMO1 has been shown to influence the generation of Amyloid-beta peptide by promoting the accumulation of BACE-1 (7). Covalent modification of Phosphatase and Tensin Homolog Deleted on Chromosome (PTEN) by SUMO1 is thought to regulate tumorigenesis by retaining PTEN at the plasma membrane, an effect that suppresses PI 3-Kinase/Akt-dependent tumor growth (8).
The ubiquitin-like SUMO1 is conjugated to a variety of proteins in the presence of Ubc9 and the SAE1/SAE2 (human) or Aos1/Uba2 (yeast) activating enzyme. SUMO1 is derived from the precursor pro-SUMO1 (Accession # NM_003352). Human SUMO1 shares 46% and 47% identity with SUMO2 and SUMO3 respectively. SUMOylation can occur without the requirement of a specific E3 ligase activity, where SUMO is transferred directly from UbcH9 to specific substrates. SUMOylated substrates are primarily localized to the nucleus (RanGAP-1, RANBP2, PML, p53, Sp100, HIPK2), but there are also cytosolic substrates (I kappa B alpha, GLUT1, GLUT4). SUMO modification has been implicated in functions such as nuclear transport, chromosome segregation, and transcriptional regulation.

假期没法联系老师呵呵。
这三种的作用都是什么。
产品主要应用：点击化学(Clickchemistry)、蛋白质组学研究中的双向荧光差异凝胶电泳(2DDIGE)和实时荧光定量PCR(RealtimePCR)。
菁染料是性能优良的荧光标记染料，摩尔吸光系数在荧光染料中是最高的。N-羟基琥珀酰亚胺酯是最常用的脂肪氨基标记试剂，广泛用于蛋白质、氨基酸多肽、抗体、核酸及其他生物分子的标记和检测。通过改变次甲基链的长度,可改变其荧光发射波长，每增加一个双键，按照Huoffman规则正好红移约100nm。
菁染料Cy3和Cy5已成为基因芯片的首选荧光标记物；另外,Cy5,Cy5.5和Cy7，Cy7.5的吸收在近红外区背景非常低，是荧光强度最高、最稳定的长波长染料，特别适合于活体小动物体内成像。但由于菁染料,尤其是不对称菁染料的合成副反应多,副产物极性相近,产物的分离提纯相当困难。菁染料特别是水溶性菁染料分子极性大,分离提纯越加困难。Lumiprobe供应脂溶性和水溶性菁染料。

分子生物学实验的染料主要涉及到核酸染料和蛋白质染料.核酸染料主要有EB（溴化乙锭,高致癌性）,goldview,sybr green（实时定量PCR时常用染料）.这些染料可以和核酸双链分子特异性结合发出强荧光而被检测到.蛋白质染料最常用的是考马斯亮蓝 R-250,硝酸银.其中硝酸银有时也用于核酸染色.
染料分为天然染料和人工染料两种。天然染料有胭脂虫红、地衣素、石蕊和苏木素等，它们多从植物体中提取得到，其成分复杂，有些至今还未搞清楚。目前主要采用人工染料，也称煤焦油染料，多从煤焦油中提取获得，是苯的衍生物。多数染料为带色的有机酸或碱类，难溶于水，而易溶于有机溶剂中。为使它们易溶于水，通常制成盐类。
染料可按其电离后染料离子所带电荷的性质，分为酸性染料、碱性染料、中性（复合）染料和单纯染料四大类。 标本干燥后即进行固定，固定的目的有三个：
1）杀死微生物，固定细胞结构。
2）保证菌体能更牢的粘附在载玻片上，防止标本被水冲洗掉。
3）改变染料对细胞的通透性，因为死的原生质比活的原生质易于染色。
前一阵子实验室开始使用一种新的核酸染料-goldview,取代原先用的溴化乙锭-EB.goldview现在是由赛百盛出售.以下摘自官方网站:
GoldViewTM核酸染料——使用说明
概述
GoldViewTM是一种可代替溴化乙锭（EB）的新型核酸染料，采用琼脂糖电泳检测DNA时，GoldViewTM与核酸结合后能产生很强的荧光信号，其灵敏度与EB相当，使用方法与之完全相同。在紫外透射光下双链DNA呈现绿色荧光，而单链DNA呈红色荧光。GoldView不仅能染DNA，也可用于染RNA。
通过Ames试验、小鼠骨髓嗜多染红细胞微核试验、小鼠睾丸精母细胞染色体畸变试验，致突变性结果均为阴性；而溴化乙锭（EB）是一种强致癌剂。因此用GoldviewTM代替EB不失为一种明智的选择。
使用方法
1.将100ml琼脂糖凝胶溶液（浓度一般为0.8%~2%）在微波炉中融化。
2.加入5µlGoldView，轻轻摇匀，避免产生气泡。
3.冷却至不烫手时倒胶，待琼脂糖凝胶完全凝固后上样电泳。
4.电泳完毕在紫外灯下观察。若使用数码相机照像记录，则关闭相机的闪光灯，放在自动档即可；若使用凝胶成像系统照相，通过调节光圈、曝光时间，选择合适的滤光片，可得到成像清晰、背景较低的照片。
注意事项
1.胶厚度不宜超过0.5cm，胶太厚会影响检测的灵敏度。
2.加入GoldView的琼脂糖凝胶反复融化可能会对核酸检测的灵敏度产生一定影响，但不明显。
3.通过凝胶电泳回收DNA片段时，建议使用GoldView染色，在自然光下切割DNA条带，避免紫外线与EB对目的DNA产生的损伤，可明显提高克隆、转化、转录等分子生物学下游操作的效率。
4.虽然未发现GoldView有致癌作用，但对皮肤、眼睛会有一定的刺激，操作时应戴上手套。
电泳结果显示GV灵敏度与EB相当
问题1.Goldview到底是不是丫啶橙？
2.赛百盛不公布其成分的原因是害怕其为丫啶橙还是出于技术保密？

氨基类染料是包含自由氨基的活性染料，染料可与活化羧酸衍生物和其他亲电子的试剂结合。比如：氨基与EDC-活化的羧基结合。
