アプリケーション

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.

アプリケーション Abreviews 特記事項
ICC/IF Use at an assay dependent concentration.
IHC-P 1/10 - 1/50. Antigen retrieval is not essential but may optimise staining.

WB Use at an assay dependent concentration.
ICC Use at an assay dependent concentration.

ターゲット情報

  • 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 dilution of 1/200, staining S100 in astrocytes (Alexa 488 secondary at 1/2000) on 30µm coronal rat brain tissue sections in free floating IHC (see protocol link for detailed description). Image shows astrocytes observed with 20x objective. Image coloured in Photoshop.

    NB: No labeling observed following omission of primary antibody.

    Sections were viewed using an Axioplan 2 Imaging microscope (Imaging Associates) fitted with 10x, 20x and 40x Plan-Neofluorobjectives (Zeiss, Germany) and images were taken using a AxioCam Hrm digital camera (Zeiss, Germany) and AxioVision software (Imaging Associates).

  • 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.

  • ab4066 at a 1/100 dilution staining rat cortical preps grown 14 days in culture, plated onto coverslips. The preps were acid/alcohol fixed for 15 minutes, blocked and then incubated with the antibody for 1 hour. Bound antibody was detected using a Alexa fluor ® 555 conjugated goat polyclonal antibody. Nuclei were visualised using DAPI (blue). Note: s100 is colocalizing around the nucleus.

    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).

As we discussed, trying an enzymatic antigen retrieval step could help with the signal.

If not, please let me know.

As for the protocol on the datasheet - this was added most likely from a collaborator or customer. Thus, these mu...

Thank you for your reply. After reviewing the customer feedback for ab4066, it appears that the customers who had obtained good WB results were using BSA as a blocking agent. The feedback we had from a customer using 5% milk was that their WB was unsuc...
