Pre-formed fibrils are an invaluable preclinical model for exploring pathogenesis of neurological diseases through aggregation of misfolded proteins. Explore our pre-seeded PFFs to use in your research.
Neural factors are a class of protein molecules with neurotrophic activity that can promote the survival and regeneration of nerve cells. Explore our series of recombinant neural factors to support the culture and differentiation of nerve cells.
Partnering with Diagnostic Biochips, we now provide solutions for in vivo electrophysiology recordings, including high-quality multi-channel electrodes and other products to facilitate high-quality, efficient analysis of neural circuit structure and function.
Protein markers are an essential component in biological research and drug development. Whether it is for protein electrophoresis or western blot, our pre-stained protein markers help you quickly determine the molecular weight of the target protein or evaluate the transfer efficiency.
Streptavidin is a tetrameric protein providing 4 high-affinity biotin binding sites. We offer a wide array of products pre-conjugated with streptavidin to support your research as well as biotinylated proteins.
Setting the corresponding isotype control antibody to detect non-specific binding can reduce the generation of false positive results and evaluate the possible influencing factors accurately in the drug development process. Explore our isotype controls for your research.
The efficacy of a therapeutic antibody depends on the Fab fragment and its binding activity to the target antigen, but also depends on the Fc fragment and its interaction with key Fc receptors.Therefore, candidates must be tested against a panel of receptors during antibody engineering. Explore our comprehensive collection of recombinant Fc receptor proteins!
Pseudoviruses are virus particles that have altered nucleic acid sequences within their genome to ensure they are replication-deficient and non-pathogenic. Explore our catalog of pseudoviruses & services!
Semaphorin-4A (SEMA4A) is also known as Semaphorin-B (SEMAB), which belongs to the semaphorin family. SEMA4A contains one Ig-like C2-type (immunoglobulin-like) domain, one PSI domain and one sema domain. SEMA4A is cell surface receptor for PLXNB1, PLXNB2, PLXNB3 and PLXND1 that plays an important role in cell-cell signaling. SEMA4A plays a role in priming antigen-specific T-cells, promotes differentiation of Th1 T-helper cells, and thereby contributes to adaptive immunity. SEMA4A also promotes phosphorylation of TIMD2 and inhibits angiogenesis. SEMA4A promotes axon growth cone collapse and inhibits axonal extension by providing local signals to specify territories inaccessible for growing axons.
