通用注释

亚单元:

Homodimer. Preferentially exists as a heterodimer or heterotetramer with S100A8 known as calprotectin (S100A8/A9). S100A9 interacts with ATP2A2. S100A9 interacts with AGER, and with the heterodimeric complex formed by TLR4 and LY96 in the presence of calcium and/or zinc ions. S100A9 binds quinoline-3-carboxamides in the presence of calcium and/or zinc ions. S100A9 interacts with beta-APP40 (beta-amyloid protein 40) peptide of APP. Calprotectin (S100A8/9) interacts with CEACAM3 and tubulin filaments in a calcium-dependent manner. Heterotetrameric calprotectin (S100A8/A9) interacts with ANXA6 and associates with tubulin filaments in activated monocytes. Calprotectin (S100A8/9) interacts with NCF2/P67PHOX, RAC1, RAC2, CYBA and CYBB (By similarity). Calprotectin (S100A8/9) interacts with NOS2 to form the iNOS-S100A8/A9 transnitrosylase complex.

功能:

S100A9 is a calcium- and zinc-binding protein which plays a prominent role in the regulation of inflammatory processes and immune response. It can induce neutrophil chemotaxis, adhesion, can increase the bactericidal activity of neutrophils by promoting phagocytosis via activation of SYK, PI3K/AKT, and ERK1/2 and can induce degranulation of neutrophils by a MAPK-dependent mechanism. Predominantly found as calprotectin (S100A8/A9) which has a wide plethora of intra- and extracellular functions. The intracellular functions include: facilitating leukocyte arachidonic acid trafficking and metabolism, modulation of the tubulin-dependent cytoskeleton during migration of phagocytes and activation of the neutrophilic NADPH-oxidase. Activates NADPH-oxidase by facilitating the enzyme complex assembly at the cell membrane, transferring arachidonic acid, an essential cofactor, to the enzyme complex and S100A8 contributes to the enzyme assembly by directly binding to NCF2/P67PHOX. The extracellular functions involve proinfammatory, antimicrobial, oxidant-scavenging and apoptosis-inducing activities. Its proinflammatory activity includes recruitment of leukocytes, promotion of cytokine and chemokine production, and regulation of leukocyte adhesion and migration. Acts as an alarmin or a danger associated molecular pattern (DAMP) molecule and stimulates innate immune cells via binding to pattern recognition receptors such as Toll-like receptor 4 (TLR4) and receptor for advanced glycation endproducts (AGER). Binding to TLR4 and AGER activates the MAP-kinase and NF-kappa-B signaling pathways resulting in the amplification of the proinflammatory cascade. Has antimicrobial activity towards bacteria and fungi and exerts its antimicrobial activity probably via chelation of Zn(2+) which is essential for microbial growth. Can induce cell death via autophagy and apoptosis and this occurs through the cross-talk of mitochondria and lysosomes via reactive oxygen species (ROS) and the process involves BNIP3. Can regulate neutrophil number and apoptosis by an anti-apoptotic effect; regulates cell survival via ITGAM/ITGB and TLR4 and a signaling mechanism involving MEK-ERK. Its role as an oxidant scavenger has a protective role in preventing exaggerated tissue damage by scavenging oxidants (By similarity). The iNOS-S100A8/A9 transnitrosylase complex is proposed to direct selective inflammatory stimulus-dependent S-nitrosylation of multiple targets such as GAPDH, NXA5, EZR, MSN and VIM by recognizing a [IL]-x-C-x-x-[DE] motif.

Secreted Cytoplasm Cytoplasm Cytoskeleton Cell membrane Peripheral membrane protein Predominantly localized in the cytoplasm. Upon elevation of the intracellular calcium level, translocated from the cytoplasm to the cytoskeleton and the cell membrane. Upon neutrophil activation or endothelial adhesion of monocytes, is secreted via a microtubule-mediated, alternative pathway (By similarity).

牛S100钙结合蛋白A9/钙粒蛋白B(S100A9)重组蛋白是否是无菌的？

蛋白试剂瓶和蛋白保存液是经过高压灭菌的，但也不能保证蛋白是完全无菌的。如果要求蛋白是无菌的，可以用0.2微米的滤器对蛋白进行过滤。

[2].

牛S100钙结合蛋白A9/钙粒蛋白B(S100A9)重组蛋白的保存缓冲液是什么？

纯化后的蛋白保存在PBS（58mM Na2HPO4, 17mM NaH2PO4, 68mM NaCl, pH7.4）里，并往里面加入500mM咪唑和10%甘油。

[3].

怎样确定牛S100钙结合蛋白A9/钙粒蛋白B(S100A9)重组蛋白的浓度？

蛋白浓度的确定没有一个统一的标准，这主要取决于蛋白的氨基酸序列。伊艾博是根据不同测试的组合来测定蛋白浓度。考马斯亮蓝法、BCA法、氨基酸序列和氨基酸全序列分析法等都用来测定蛋白浓度。

[4].

牛S100钙结合蛋白A9/钙粒蛋白B(S100A9)重组蛋白蛋白保存条件是怎样的？

蛋白应保存在 -20℃或 -80℃条件下，为了避免反复冻融，可以将蛋白分装成小份保存。

[5].

牛S100钙结合蛋白A9/钙粒蛋白B(S100A9)重组蛋白是否可以用于活体实验？

重组蛋白没有用于任何的活体实验，因此蛋白的活性和半衰期是不确定的。

[6].

牛S100钙结合蛋白A9/钙粒蛋白B(S100A9)重组蛋白的保质期是多久？

在适当的保存条件下，从购买之日起蛋白可以稳定保存6-12个月。适当的保存条件是:蛋白保存在-20°C o或 -80℃，保证蛋白的保存浓度高于0.1mg/ml，限制蛋白反复冻融的次数。我们公司常规的质量检测保证所有产品在销售时都有可接受的生物活性。但是我们不能控制终端用户蛋白的保存条件。如果产品在有效期内出现问题，请联系我们的技术支持。

[7].

你们蛋白和抗体的报价是怎么样的？

我们将根据你需要的蛋白和抗体的大小进行报价。

[8].

牛S100钙结合蛋白A9/钙粒蛋白B(S100A9)重组蛋白是否能够提供蛋白片段？

我们现有的人的蛋白的序列可以有很多。你可以选择你感兴趣的靶向部分，我们将会按您的需求提供蛋白和抗体。

[9].

牛S100钙结合蛋白A9/钙粒蛋白B(S100A9)重组蛋白的货期或发货时间一般是多长？

具体指标的货期需要确定。最快一周，最长可能一个月。
