硫酸盐乳胶微珠,4% w/v,5 μm

微球(又称乳胶微球或乳胶颗粒), 是胶体粒度范围内的球形颗粒, 由诸如聚苯乙烯等非晶态聚合物形成。聚苯乙烯链在微珠中自行排列,因此其表面具有较强的疏水性,使其成为可以吸附蛋白质等物质的理想材料。这些硫酸盐乳胶微球可以通过硫酸电荷稳定化。在某些情况下,羟基和羧基也少量结合到聚合物链。硫酸基的 pKa为了解更多信息

微球(又称乳胶微球或乳胶颗粒), 是胶体粒度范围内的球形颗粒, 由诸如聚苯乙烯等非晶态聚合物形成。聚苯乙烯链在微珠中自行排列,因此其表面具有较强的疏水性,使其成为可以吸附蛋白质等物质的理想材料。

这些硫酸盐乳胶微球可以通过硫酸电荷稳定化。在某些情况下,羟基和羧基也少量结合到聚合物链。硫酸基的 pKa为 <2,因此颗粒在酸性培养基中是稳定的。在高达几乎为 0.30 M 单价电解质浓度中,颗粒悬浮液是稳定的,因此可以在生理离子强度培养基中使用。但是,它们是疏水性颗粒,如果存在低浓度的二价或三价阳离子会发生聚集,除非通过亲水性包被进行稳定化。硫酸盐乳胶适用于粒度分析仪器校准,并且也适用于依靠抗原或抗体物理吸附的诊断测试系统。

微球有许多不同尺寸大小和不同表面功能
25 种尺寸可供选择—0.02 微米到 16 微米
20 种不同表面—用于与几乎所有材料偶联
不含表面活性剂—超净
各种数量—从毫升到 500 升

微球的关键应用
仪器校准(流式细胞仪、显微镜、HTS、HCS)
流量检测(微流体、血流、水流和气流)
细胞生物学示踪剂(细胞分化与细胞示踪)
免疫分析(凝集试验、ELISA、颗粒捕获及造影剂)

Abstract
Synthetic CD4+ T cell-targeted antigen-presenting cells elicit protective antitumor responses.
Authors:Caserta S, Alessi P, Guarnerio J, Basso V, Mondino A,
Journal:Cancer Res
PubMed ID:18413771
CD4(+) helper T cells are critical for protective immune responses and yet suboptimally primed in response to tumors. Cell-based vaccination strategies are under evaluation in clinical trials but limited by the need to derive antigen-presenting cells (APC) from patients or compatible healthy donors. To overcome these limitations, we developed CD4(+) ... More
Stored Fas ligand, a mediator of rapid CTL-mediated killing, has a lower threshold for response than degranulation or newly synthesized Fas ligand.
Authors:He JS, Gong DE, Ostergaard HL,
Journal:J Immunol
PubMed ID:19949069
'CTL lyse target cells through the release of cytolytic granule mediators and expression of the death receptor ligand Fas ligand (FasL). We previously demonstrated that FasL is stored in vesicles distinct from cytolytic granules and is translocated to the cell surface within 15 min of TCR stimulation, followed by a ... More
Antigen-experienced CD4(+) T cells limit naïve T-cell priming in response to therapeutic vaccination in vivo.
Authors:Schiering C, Guarnerio J, Basso V, Muzio L, Mondino A,
Journal:Cancer Res
PubMed ID:20631073
'CD4(+) T cells play a central role in protective immunity. In a mouse tumor model, we previously found that tumor growth elicits natural CD4(+) T-cell responses, but impedes therapeutic vaccination. We show here that inhibition of vaccine-mediated naïve T-cell priming is due to the presence of a minor but distinct ... More
Chromogranin A regulates tumor self-seeding and dissemination.
Authors:Dondossola E, Crippa L, Colombo B, Ferrero E, Corti A,
Journal:Cancer Res
PubMed ID:22139379
Cancer progression involves the seeding of malignant cells in circulation and the colonization of distant organs. However, circulating neoplastic cells can also reinfiltrate the tumor of origin. This process, called  ... More
Ezrin and moesin function together to promote T cell activation.
Authors:Shaffer MH, Dupree RS, Zhu P, Saotome I, Schmidt RF, McClatchey AI, Freedman BD, Burkhardt JK,
Journal:J Immunol
PubMed ID:19124745
The highly homologous proteins ezrin, radixin, and moesin link proteins to the actin cytoskeleton. The two family members expressed in T cells, ezrin and moesin, are implicated in promoting T cell activation and polarity. To elucidate the contributions of ezrin and moesin, we conducted a systematic analysis of their function ... More
