  • 特記事項

    Spleen cells from immunised BALB/c mice were fused with cells of the NSO/U myeloma cell line. This clone has been described reacting with paraffin embedded material following PLP fixation (see Whiteland et al., 1995). It only labels B cells among thoracic duct lymphocytes, with little labelling in bone marrow and none on thymocytes (Barclay et al., 1987).

    This antibody clone is manufactured by Abcam. If you require a custom buffer formulation or conjugation for your experiments, please contact orders@abcam.com.

    The Life Science industry has been in the grips of a reproducibility crisis for a number of years. Abcam is leading the way in addressing this with our range of recombinant monoclonal antibodies and knockout edited cell lines for gold-standard validation. Please check that this product meets your needs before purchasing.

ターゲット情報

  • 機能

    Protein tyrosine-protein phosphatase required for T-cell activation through the antigen receptor. Acts as a positive regulator of T-cell coactivation upon binding to DPP4. The first PTPase domain has enzymatic activity, while the second one seems to affect the substrate specificity of the first one. Upon T-cell activation, recruits and dephosphorylates SKAP1 and FYN. Dephosphorylates LYN, and thereby modulates LYN activity.

  • 関連疾患

  • 配列類似性

    Belongs to the protein-tyrosine phosphatase family. Receptor class 1/6 subfamily.

      Lewis rat splenocytes stained with ab33933 (right) or mouse IgG1κ (ab170190) isotype (left). Lewis rat splenocytes were incubated for 30 min on ice in 1x PBS / 10 % rat serum to block FC receptors and non-specific protein-protein interaction followed by the antibody (ab33933) or mouse IgG1κ isotype (ab170190) (1x106 in 100µl at 0.2 µg/ml) for 30 min on ice.

      The secondary antibody Goat anti-mouse IgG H&L (Alexa Fluor ® 488, pre-adsorbed) (ab150177) was used at 1/2000 dilution for 30 min at 4°C. The cells were simultaneously stained with CD3 antibody.

      Acquisition of >30,000 events were collected using a 50 mW Blue laser (488nm) and 530/30 bandpass filter. Events were gated on viable lymphocytes.

      IHC image of CD45RA staining in a section of frozen normal Rat Spleen.

      The section was fixed using 10% formaldehyde in 1XPBS for 10 minutes. No antigen retrieval step was performed prior to staining. Non-specific protein-protein interactions were then blocked in TBS containing 0.025% (v/v) Triton X-100, 0.3M glycine and 1% (w/v) BSA for 1h at room temperature.  The section was then incubated overnight at +4°C in TBS containing 0.025% (v/v) Triton X-100 and 1% (w/v) BSA with ab33933 at 1µg/ml. The section was then incubated with ab150117 (Goat Anti-Mouse IgG H&L (Alexa Fluor® 488) preabsorbed, (Shown in green) 1/1000) for 1 hour at room temperature. DAPI was used to stain the cell nuclei (blue). The secondary-only control insert image is taken from an identical assay without primary antibody. The section was then mounted using Fluoromount®.

      Image was taken with a confocal microscope (Leica-Microsystems, TCS SP8).

      For IHC staining systems (automated and non-automated), customers should optimize variable parameters such as antibody concentrations and incubation times.

    Answer

    Thank you for contacting us.

    I have emailed the lab to see if they have an IHC-P image they can share, and will let you know when I hear back from them.

    The reference I had mentioned is as follows:

    Question

    Could you provide an IHC-P protocol for ab33933 and ab33934.

    Read More
    Answer

    Thank you for your recent telephone enquiry. I have obtained the following general testing method from the originator of ab33933 and ab33934. Please note that this protocol is a guideline only and may need to be optimized in your laboraotry. I hope this will be helpful to you. Should you have any further questions, please do not hesitate to contact us. 1. De-paraffinise sections thoroughly in Xylene/synthetic solvent and hydrate through graded series of alcohols. 2. Wash twice in TBS. 3. If required, treat with 0.3% (w/v) hydrogen peroxide in methanol for 30 minutes to block endogenous peroxidase activity (2% w/v H2O2/Methanol can be used for a shorter time if preferred). 4. Wash once in TBS. 5. If required, include appropriate antigen retrieval step to enhance immunostaining. 6. Wash once in TBS. 7. Incubate sections for 10 minutes in 10% normal serum from species in which secondary antibody was raised. 8. Tap excess serum off the slides before staining. 9. Incubate sections in primary antibody for at least 1 hour at room temperature in a humid chamber or overnight at 4°C. Wash three times in TBS. 10. Add enzyme conjugated secondary antibody at recommended dilution (see specific datasheet for details). Incubate for at least 30 minutes at room temperature. 11. Wash three times in TBS. 12. Incubate in appropriate substrate solution for recommended period of time (we would recommends the use of DAB substrate with HRP conjugated antibodies, and Fast Red / Napthol AS-MX for Alkaline Phosphatase conjugated antibodies). 13. Wash once in water. 14. Counterstain in haematoxylin, 2-10 minutes. ‘Blue’ in running water for 5 minutes. 15. Mount in aqueous mounting medium or alternatively dehydrate through alcohols and xylene/solvent and mount in synthetic mountant. Notes: NB. Note that certain substrates are soluble in alcohol - please refer to supplier information for details. Appropriate control samples should always be included. It may be useful to include a control in which no primary antibody is used at all, to determine any non-specific binding of the secondary reagent to the target tissue. Solutions used: TBS (stock solution ×10 concentrated) Sodium chloride 87.66 g, Tris 60.55 g, Distilled water 1 litre. Adjust pH to 7.5 using concentrated HCl.
