Our Abpromise guarantee covers the use of ab4066 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|ICC/IF||Use at an assay dependent concentration. PubMed: 23624931|
|IHC-P||1/10 - 1/50. Antigen retrieval is not essential but may optimise staining.|
|IHC-Fr||1/200 - 1/500.|
|WB||Use at an assay dependent concentration.|
機能Weakly binds calcium but binds zinc very tightly-distinct binding sites with different affinities exist for both ions on each monomer. Physiological concentrations of potassium ion antagonize the binding of both divalent cations, especially affecting high-affinity calcium-binding sites.
組織特異性Highly prevalent in heart. Also found in lesser quantities in skeletal muscle and brain.
配列類似性Belongs to the S-100 family.
Contains 2 EF-hand domains.

ab4066 at a 1/200 dilution staining rat spinal cord tissue sections by Immunohistochemistry (Frozen sections). Rats were transcardially perfused with 4% PFA, the tissue was post fixed 1 hour in 4% PFA then 30% sucrose for three days. 20um sections were cut with cryostat. The antibody was incubated with the tissue sections for 18 hours and then bound antibody was detected using an Alexa Fluor ® 555 conjugated goat polyclonal antibody.

Performed under reducing conditions.
Observed band size: 15,18,21 kDa why is the actual band size different from the predicted?
Exposure time: 2 minutes
The extra band at 18kDa may be a result of the protein's thermolabile properties. The band at 21 kDa maybe a dimer of s100a and s100b and the 10/15 kDa may be the subunits. However, there are also references to suggest these may be immunoreactive proteins with differing molecular weights depending on proliferative or differentiated state of the cell (Anat Embryol (Berl). 1997 Nov;196(5):403-16).
