    (progressive or stable disease, PD/SD)

    (partial or complete remission, PR/CR)

    The level of ALDH1 was tested by immunohistochemistry staining in paraffin-embedded tissue sections. Rabbit monoclonal ALDH1A1 antibody (ab52492, Abcam) used at a 1:100 dilution.

  • Sections of the proximal (top) and distal (bottom) mouse colon were assayed for protein expression of ALDH1A1.

    Signals yielded by immunohistochemical staining (red) are shown in merged images with DAPI staining (blue). Representative data are shown for three independent experiments. Arrowheads show positive cells for ALDH1A1 in the distal colon. Scale bars, 50 μm.

    Colonic tissues were fixed overnight at 4°C in 4% paraformaldehyde, sequentially dehydrated in 10, 15 and 20% sucrose in PBS, and embedded in OCT compound. Colonic organoids were fixed together with surrounding collagen type I gel and processed in the same manner. Frozen sections of 8-μm thickness were subjected to immunohistochemistry using ab52492.

  • Immunocytochemistry/ Immunofluorescence analysis of HepG2 (Human liver hepatocellular carcinoma cell line) cells labeling ALDH1A1 with ab52492 at 1/500 dilution (4 μg/ml).

    Cells were fixed in 100% methanol. ab150077, an AlexaFluor®488 Goat anti-Rabbit secondary antibody was used at 1/1000 dilution (2 μg/ml). ab195889, Anti-alpha Tubulin antibody [DM1A] - Microtubule Marker (Alexa Fluor® 594) was used to counterstain at 1/200 dilution (2.5 μg/ml). DAPI was used as nuclear counterstain.

  • Overlay histogram showing HepG2 (Human liver hepatocellular carcinoma cell line) cells stained with ab52492 (red line).

    The cells were fixed with 80% methanol (5 minutes) and then permeabilized with 0.1% PBS-Tween for 20 minutes. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab52492, 1/1000 dilution) for 30 minutes at 22°C. The secondary antibody used was Alexa Fluor® 488 goat anti-rabbit IgG (H&L) (ab150077) at 1/2000 dilution for 30 minutes at 22°C. Isotype control antibody (black line) was rabbit IgG (monoclonal) (0.1μg/1x106 cells) used under the same conditions. Unlabeled sample (blue line) was also used as a control.

    Acquisition of >5,000 events were collected using a 20mW Argon ion laser (488nm) and 525/30 bandpass filter.

Vielen Dank für Ihren Anruf.

Ich freue mich Ihnen nun bestätigen zu können, dass die Konzentration 0.130 mg/mL ist. (von Lot 1315178).

Ich würde Sie außerdem noch gerne darauf hinweisen, dass ich für eine effiziente Konjugierung mit ab102908 (EasyLink PerCP Conjugation Kit (3 x 10µg PerCP)) eine Aufreinigung von ab52492 dringend empfehle.

ab52492 ist Zellkulturüberstand, der viele andere Proteine enthält. Das Easylink Kit wird alle zugänglichen Amine mit PerCP konjugieren, und somit auch die anderen Proteine in der Antikörperlösung.

Ich kann Ihnen das folgende Kit empfehlen:

ab109207 (Antibody TCS Purification Kit)

https://www.abcam.com/index.html?datasheet=109207 (or use the following: https://www.abcam.com/index.html?datasheet=109207).

Ich hoffe, diese Information was hilfreich und wünsche Ihnen viel Erfolg für Ihre Experimente.

Thank you for contacting Abcam.

Based on the information we have for ab52492, we would recommend that you use heat mediated antigen retrieval with sodium citrate. I have attached our Abcams protocol booklet that contains information about this methods and also contains recipes for the solutions aswell.

If there is anything else I can help you with, please let me know.

Thank you for contacting Abcam regarding ab52492.

I am sorry that you are experiencing some difficulties detecting the correct molecular weight band in WB with this antibody. I have reviewed the protocol information you provided and I am not sure that any changes to this would improve your results. Have you completely denatured and reduced the protein?I would recommend boiling for10 minutes and be sure you have included DTT or beta-mercaptoethanol in the sample buffer.

Another explanationis that this protein is subject to post-translational modifications, acetylation in particular at 10 different residues, resulting in a shift of molecular weight.

Unfortunately a blocking peptide is not available, but I can provide the protein sequence if you were interested in synthesizing your own.

I hope this information is helpful. Please do not hesitate to contact me if you have any additional questions or concerns.

Thank you for your phone call today. I contacted the lab and was given the protocol used for IHC testing. Antigen retrieval was performed using pH 6 citrate buffer for 20-30 minutes in a heated rice cooker. The exact dilution of this antibody for IHC is variable, but I recommend starting with 1:100 dilution. I have attached the full protocol to this email. I hope this information is helpful, but please let me know if you have further questions.
