使用EasySep™小鼠B细胞分选试剂盒,通过免疫磁珠负选技术,可轻松高效地从脾脏单细胞悬液或其他组织样本中分离高纯度小鼠B细胞。EasySep™技术结合单克隆抗体的特异性和无柱磁分选系统的简便性,已在发表的研究中广泛应用超过20年。

在此 EasySep™ 负选方案中,非目的细胞通过抗体复合物与磁珠标记。表面表达以下标志物的非目的细胞将被特异性去除:CD11b、CD4、CD8a、Ly6G/C、Ter119、CD43、CD49b和CD90.2。通过EasySep™磁极,将这些被磁珠标记的细胞与未被标记的目的细胞分离,接着简单的将目的细胞倾倒或吸取至一个新的试管中。仅需15分钟可完成磁珠分选,分选得到的B细胞可直接用于流式细胞术、细胞培养及基于细胞的实验等下游应用。

如需分选表达CD11b或CD43的B细胞,建议使用EasySep™小鼠Pan-B细胞分选试剂盒(产品号#19844)。

常见问题

Can EasySep™ Streptavidin RapidSpheres™ be used for either positive or negative selection?

Currently, EasySep™ Streptavidin RapidSphere™ kits are only available for negative selection and work by targeting and removing unwanted cells.

How does the separation work?

Streptavidin RapidSphere™ magnetic particles are crosslinked to unwanted cells using biotinylated antibodies. When placed in the EasySep™ Magnet, labeled cells migrate to the wall of the tube. The unlabeled cells are then poured off into a new tube.

Which columns do I use?

The EasySep™ procedure is column-free. That's right - no columns!

How can I analyze the purity of my enriched sample?

The Product Information Sheet provided with each EasySep™ kit contains detailed staining information.

Can EasySep™ Streptavidin RapidSphere™ separations be automated?

Yes. RoboSep™, the fully automated cell separator, automates all EasySep™ labeling and cell separation steps.

Are cells isolated using EasySep™ RapidSphere™ products FACS-compatible?

Yes. Desired cells are unlabeled and ready to use in downstream applications, such as FACS analysis.

Can I alter the separation time in the magnet?

Yes; however, this may impact the kit's performance. The provided EasySep™ protocols have already been optimized to balance purity, recovery and time spent on the isolation.

Co-modulation of T cells and B cells enhances the inhibition of inflammation in experimental hypersensitivity pneumonitis. O. Courtemanche et al. Respiratory research 2022 oct

Abstract

BACKGROUND Hypersensitivity pneumonitis (HP) is an interstitial lung disease characterized by antigen-triggered neutrophilic exacerbations. Although CD4+ T cells are sufficient for HP pathogenesis, this never translated into efficient T cell-specific therapies. Increasing evidence shows that B cells also play decisive roles in HP. Here, we aimed to further define the respective contributions of B and T cells in subacute experimental HP. METHODS Mice were subjected to a protocol of subacute exposure to the archaeon Methanosphaera stadmanae to induce experimental HP. Using models of adoptive transfers of B cells and T cells in Rag1-deficient mice and of B cell-specific S1P1 deletion, we assessed the importance of B cells in the development of HP by evaluating inflammation in bronchoalveolar lavage fluid. We also aimed to determine if injected antibodies targeting B and/or T cells could alleviate HP exacerbations using a therapeutic course of intervention. RESULTS Even though B cells are not sufficient to induce HP, they strongly potentiate CD4+ T cell-induced HP?‘associated neutrophilic inflammation in the airways. However, the reduction of 85% of lung B cells in mice with a CD19-driven S1P1 deletion does not dampen HP inflammation, suggesting that lung B cells are not necessary in large numbers to sustain local inflammation. Finally, we found that injecting antibodies targeting B cells after experimental HP was induced does not dampen neutrophilic exacerbation. Yet, injection of antibodies directed against B cells and T cells yielded a potent 76% inhibition of neutrophilic accumulation in the lungs. This inhibition occurred despite partial, sometimes mild, depletion of B cells and T cells subsets. CONCLUSIONS Although B cells are required for maximal inflammation in subacute experimental HP, partial reduction of B cells fails to reduce HP-associated inflammation by itself. However, co-modulation of T cells and B cells yields enhanced inhibition of HP exacerbation caused by an antigenic rechallenge.
Immune correlates of protection following Rift Valley fever virus vaccination. J. D. Doyle et al. NPJ vaccines 2022 oct

Abstract

Rift Valley fever virus (RVFV) is a hemorrhagic fever virus with the potential for significant economic and public health impact. Vaccination with an attenuated strain, DelNSsRVFV, provides protection from an otherwise lethal RVFV challenge, but mechanistic determinants of protection are undefined. In this study, a murine model was used to assess the contributions of humoral and cellular immunity to DelNSsRVFV-mediated protection. Vaccinated mice depleted of T cells were protected against subsequent challenge, and passive transfer of immune serum from vaccinated animals to na{\{i}}ve animals was also protective demonstrating that T cells were dispensable in the presence of humoral immunity and that humoral immunity alone was sufficient. Animals depleted of B cells and then vaccinated were protected against challenge. Total splenocytes but not T cells alone B cells alone or B??+??T cells harvested from vaccinated animals and then transferred to na{\"{i}}ve animals were sufficient to confer protection suggesting that multiple cellular interactions were required for effective cellular immunity. Together these data indicate that humoral immunity is sufficient to confer vaccine-mediated protection and suggests that cellular immunity plays a role in protection that requires the interaction of various cellular components."
Pre-Germinal Center Interactions with T Cells Are Natural Checkpoints to Limit Autoimmune B Cell Responses. K. A. Parham et al. Journal of immunology (Baltimore, Md. : 1950) 2022 nov

Abstract

Interactions with Ag-specific T cells drive B cell activation and fate choices that ultimately determine the quality of high-affinity Ab responses. As such, these interactions, and especially the long-lived interactions that occur before germinal center formation, may be important checkpoints to regulate undesirable responses. Using mouse model Ag systems, we directly observed interactions between T and B cells responding to the self-antigen myelin oligodendrocyte glycoprotein (MOG) and found that they are of lower quality compared with interactions between cells responding to the model foreign Ag nitrophenyl-haptenated OVA. This was associated with reduced expression of molecules that facilitate these interactions on the B cells, but not on T cells. B cell expression of these molecules was not dictated by the T cell partner, nor could the relative lack of expression on MOG-specific (MOG-sp.) B cells be reversed by a multivalent Ag. Instead, MOG-sp. B cells were inherently less responsive to BCR stimulation than MOG-non-sp. cells. However, the phenotype of MOG-sp. B cells was not consistent with previous descriptions of autoimmune B cells that had been tolerized via regular exposure to systemically expressed self-antigen. This suggests that alternate anergy pathways may exist to limit B cell responses to tissue-restricted self-antigens.
