Recombinant Human Di-Ub (K48-linked) FRET TAMRA Pos1, 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.

Reconstitution Calculator
Background: Di-Ubiquitin
With a predicted molecular weight of 17 kDa, Di-Ubiquitin is composed of two Ubiquitin monomers that are covalently linked through an isopeptide bond, which typically form between a lysine residue of one Ubiquitin molecule and the C-terminal glycine residue of another Ubiquitin molecule (1). Each human Ubiquitin monomer is 76 amino acids (aa) in length and shares 96% and 100% aa identity with yeast andmouse Ubiquitin, respectively (2). Ubiquitin has seven lysine residues that can participate in the formation of poly-Ubiquitin chains. The specific lysine residue used in Ubiquitin conjugation is thought to determine the function of poly-ubiquitination in cellular processes such as protein degradation, signaling, and trafficking (3-8).
Linkage specific di-Ubiquitin is a substrate for enzymes that cleave the isopeptide linkage between two Ubiquitin molecules. These FRET-based DUB substrates with isopeptide bonds between Ubiquitin moieties are superior to gel densitometry assays. Since DUBs recognize and cleave substrates with specific steric conditions, each substrate varies in the position of the fluorophore and quencher and must be empirically tested for individual enzymes.

病毒液通过pre-filterdisc的时候是不是要制造一个真空环境产生压力差使液体通过？这个时候是用自备的针管还是试剂盒配的5毫升的针管啊？
从1～2个T75培养皿的感染细胞培养液中纯化腺病毒
产品简介
本系列试剂盒可快速，高效地从腺病毒感染的细胞培养液中分离纯化腺病毒，相比于传统CsCl超速离心的腺病毒病毒纯化方式（需要24个小时才能完成纯化），本试剂盒可以在1个小时内完成病毒纯化，操作简单，快速，纯化率高，纯化到的病毒颗粒可直接用于下游实验，如细胞和动物感染。
产品特点
?操作简单，快速，可以在1个小时内完成病毒纯化，不依赖于超速离心操作。
?纯化效率高：小量纯化，可从1~2个T75瓶培养的细胞培养液中纯化病毒颗粒高达1x1012VPs
?每个纯化柱，可以重复利用一次，用于纯化相同种类的腺病毒。
保存条件
纯化柱和脱盐柱保存于4℃，其它组分室温保存。

试剂里面含有的是病毒的抗原，现在基本都是人工合成或提取的，跟病毒完全是两回事
如果用组织DNA提取试剂盒，提出来的就是组织细胞的DNA了
主要有： 1.磁珠法核酸提取试剂盒2.磁珠法提取DNA试剂盒3.DNA提取试剂盒（离心柱法）4.磁珠法RNA提取试剂盒5.RNA提取试剂盒（离心柱法）6.磁珠法植物基因组DNA提取试剂盒7.反转录试剂盒8.胶回收试剂盒9.PCR纯化试剂盒10.病毒核酸提取试剂盒
