Recombinant Human His6-Josephin-1 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: Josephin-1/JOSD1
Josephin-1 is a member of the Machado-Joseph Disease (MJD) family of cysteine proteases, whose other members include Ataxin-3, Ataxin-3-like, and Josephin-2. 202 amino acids long with a predicted molecular weight of 23 kDa, Josephin-1 shares 97% identity with its mouse and rat orthologues. When ubiquitinated, Josephin-1 is capable of cleaving K48- and K63-linked polyubiquitin chains in vitro. Biologically, this enzyme may act to increase macropinocytosis and suppress clathrin- and caveolae-mediated endocytosis.

1. 姜黄素是一个典型的HAT抑制剂。
2. 针对P300: 在大约10年前，Cole和他的同事设计出了一种p300/CBP抑制剂，发表在nature杂志上。
希望能帮到你，望采纳！
1、组成成分：
A、1×TE缓冲液：10mmol/LTris.Cl；1mmol/LEDTA，pH8.0。
B、1×TAE缓冲液：40mmol/LTris-乙酸；2mmol/LEDTA，pH8.0。
C、1×TBE缓冲液：45mmol/LTris-硼酸；1mmol/LEDTA，pH8.0。
2、用途：
A、TE缓冲液：一般用作溶解剂或保持剂，常用于溶解DNA，能稳定储存DNA。
B、TAE缓冲液:生物学中使用最广泛的核酸电泳缓冲液，主要用于DNA的琼脂糖凝胶电泳。
C、TBE缓冲液：生物学中常用的核酸电泳缓冲液，主要用于DNA的琼脂糖凝胶电泳。
3、TAE和TBE缓冲液的选择：
TAE和TBE缓冲液都可以用于DNA的琼脂糖凝胶电泳，两者各有利弊，应根据实际情况选择不同的缓冲液。
4、注意：
TBE浓溶液长时间存放后会形成沉淀物，出现沉淀后应予以废弃。
现在不少文献和讲座都提到使用化学成份限定的supplement代替蛋白水解物，大家有什么经验可以分享或者交流的吗？

琼脂，学名琼胶，英文名（agar），又名洋菜(agar-agar）、海东菜、冻粉、琼胶、石花胶、燕菜精、洋粉、寒天、大菜丝，是植物胶的一种，常用海产的麒麟菜、石花菜、江蓠等制成，为无色、无固定形状的固体，溶于热水。在食品工业中应用广泛，亦常用作细菌培养基。为什么叫琼脂，主要是用海南的麒麟菜或石花菜制作出来的。海南的简称就是琼。琼脂特性：琼脂的最有用特性是它的凝点和熔点之间的温度相差很大。它在水中需加热至95℃时才开始熔化，熔化后的溶液温度需降到40℃时才开始凝固，所以它是配制固体培养基的最好凝固剂。用琼脂配制的固体培养基，可用以进行高温培养而不熔化，在凝固之前接种时，也不致将培养物烫死。因此，琼脂是制备各种生物培养基中应用最广泛的一种凝固剂。琼脂的浓度，通常是液体培养基的1～1.5%。向左转|向右转
天然产物，大多都有颜色，
存在干扰，多数情况下需要做样品的阴性对照，
尽量能用荧光的方法，
之前我们做过，将两个试剂盒的方法合并后，做的，
效果还可以
欧美国家是否有相关权威的抗生素使用规范？如果有，请提供，最好是中英对照的，相关网站也可以
