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.

请各位大侠给予帮助！！
谢谢！！
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)。
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。

健那绿染液是一种活体染液，实验对象必须是活细胞，健那绿可以使活细胞中的线粒体呈现蓝绿色，而细胞质接近无色。
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。
而且样品中的无水硫酸钠未变色,而做标准曲线的五个和空白对照的变为蓝色了,请高手指教,多谢!
还有,是否变蓝对测定结果有影响吗?
谢了哈
欢迎你！请下次规范发贴:)

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。
