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!
Avidin, a tetrameric glycoprotein from egg white, binds biotin (vitamin H) with remarkably high affinity; Streptavidin, an avidin-like protein from Streptomyces avidinii, also binds biotin strongly; Mushroom avidin is derive from mushroom (Pleurotus cornucopiae), and is a fungal avidin-like protein that binds biotin with high affinity.
A drawback specific to avidin is its high level of non-specific binding to various biological components at physiological pH. Mushroom avidin shows a remarkably high affinity for biotin, like avidin and streptavidin. Mushroom avidin is a tetrameric protein and each subunit binds biotin with high affinity. It has higher thermo stability than those of avidin and streptavidin, and shows less nonspecific binding than avidin. The isoelectric point of Mushroom avidin is 7.4, lower than avidin (10.0), and slightly higher than that of streptavidin (6.0-7.5). The Tm (temperature of half-life period of biotin binding activity after heat treatment) value of Mushroom avidin is 85¡æ, higher than avidin from egg (79¡æ) and streptavidin (74¡æ). The Mushroom avidin - biotin interaction is widely employed as a universal tool in numerous biotechnological applications. For example, like avidin, it can be applied for affinity chromatography, ELISA, immunohistochemistry and Western Blotting, an so on.
