Western blot analysis of rat brain (lane 1) and mouse brain (lane 2). Anti- S100B antibody (clone 11C12E12 ) was used, followed by HRP Goat anti-mouse IgG (minimal x-reactivity) antibody. Purified anti-GAPDH antibody was used as a loading control. We are not sure about the specificity of the high molecular weight band.

Description

S100B is glial-specific. It has been shown that it is only expressed by a subtype of mature astrocytes that ensheath blood vessels, and by NG2-expressing cells. This protein may function in neurite extension, stimulation of Ca2+ fluxes, inhibition of PKC-mediated phosphorylation, astrocytosis and axonal proliferation, and inhibition of microtubule assembly. In the developing central nervous system (CNS), it acts as a neurotrophic factor and neuronal survival protein. In the adult organism, it is usually elevated due to nervous system damage, which makes it a potential clinical marker. S100B is secreted by astrocytes or can spill from injured cells and enter the extracellular space or bloodstream. Serum levels of S100B increase in patients during the acute phase of brain damage. Over the last decade, S100B has emerged as a candidate peripheral biomarker of blood–brain barrier (BBB) permeability and central nervous system injury.

Related FAQs

If an antibody clone has been previously successfully used in IBEX in one fluorescent format, will other antibody formats work as well?

It’s likely that other fluorophore conjugates to the same antibody clone will also be compatible with IBEX using the same sample fixation procedure. Ultimately a directly conjugated antibody’s utility in fluorescent imaging and IBEX may be specific to the sample and microscope being used in the experiment. Some antibody clone conjugates may perform better than others due to performance differences in non-specific binding, fluorophore brightness, and other biochemical properties unique to that conjugate.

Will antibodies my lab is already using for fluorescent or chromogenic IHC work in IBEX?

Fundamentally, IBEX as a technique that works much in the same way as single antibody panels or single marker IF/IHC. If you’re already successfully using an antibody clone on a sample of interest, it is likely that clone will have utility in IBEX. It is expected some optimization and testing of different antibody fluorophore conjugates will be required to find a suitable format; however, legacy microscopy techniques like chromogenic IHC on fixed or frozen tissue is an excellent place to start looking for useful antibodies.

Are other fluorophores compatible with IBEX?

Over 18 fluorescent formats have been screened for use in IBEX, however, it is likely that other fluorophores are able to be rapidly bleached in IBEX. If a fluorophore format is already suitable for your imaging platform it can be tested for compatibility in IBEX.

The same antibody works in one tissue type but not another. What is happening?

Differences in tissue properties may impact both the ability of an antibody to bind its target specifically and impact the ability of a specific fluorophore conjugate to overcome the background fluorescent signal in a given tissue. Secondary stains, as well as testing multiple fluorescent conjugates of the same clone, may help to troubleshoot challenging targets or tissues. Using a reference control tissue may also give confidence in the specificity of your staining.

How can I be sure the staining I’m seeing in my tissue is real?

In general, best practices for validating an antibody in traditional chromogenic or fluorescent IHC are applicable to IBEX. Please reference the Nature Methods review on antibody based multiplexed imaging for resources on validating antibodies for IBEX.
