  • Anti-MASH1/Achaete-scute homolog 1 antibody (ab38556) at 1/500 dilution + Mouse lung tissue lysate

    Predicted band size: 25 kDa
    Observed band size: 25 kDa
    Additional bands at: 15 kDa, 28 kDa, 45 kDa (possible dimer), 55 kDa (possible dimer). We are unsure as to the identity of these extra bands.

  • Immunofluorescence analysis of mouse adult NSCs derived from SVZ, staining TTF1 with ab38556.

    Cells were fixed with Zamboni's fixative, permeabilized with 0.5% Triton X-100 and blocked with 3% goat serum for 2 hours at 20°C. Samples were incubated with primary antibody (1/500 in 3% goat serum) for 18 hours at 4°C. An AlexaFluor®488-conjugated goat anti-rabbit polyclonal IgG (1/500) was used as the secondary antibody.

Please thank your customer for getting back to us. I am very happy to hear that the staining with Anti-MASH1/Achaete-scute homolog 1 antibody gives a good result.

The image shows the nuclear localization of the protein very nicely.

Maybe your customer would like to write an Abreview about their experiments and earn Abpoints that they can redeem.

Please let me know if I can be of any more help.

Thank you and your customer for taking the time to complete our questionnaire and contact us. I am sorry to hear your customer has had difficulty obtaining satisfactory results from this antibody.

The details your customer has kindly provided will enable us to investigate this case for your customer and this is also helpful in our records for monitoring of quality.

Reviewing this case, I would like to offer some suggestions to help optimize the results from these antibodies.

1.) Both antibodies were used after PFA fixation and paraffin wax embedding anda 10 mM sodium citrate, pH 6.0 antigen retrieval.

2.) I suggest to lower the concentration of tritonX to 0.1 to 0.2% for 10 minutes since it is a very harsh detergent and might damage the target protein.

3.) I can also suggest to use a standard tissue as positive control in case the neurospheres are difficult to handle.

4.) I attached the protocol these two antibodies were used with to this email for your information. It is a fairly standard protocol and might therefore need optimization when extraordinary samples like neurospheres are used.

We are happy to offer this technical support. In the event that a product is not functioning in the applications cited on the product data sheet (and the problem has been reported within 6 months of purchase), we will be pleased to provide a credit note, free of charge replacement or refund.

I hope this information is helpful, thank you and your customer for your cooperation. Should the suggestions not improve the results, please do not hesitate to contact me again with the further requested details.

Muchas gracias por tu respuesta.

He comentado el protocolo seguido en IHC-P con mis compañeros del laboratorio, para tratar de entender el problema ocurrido con Anti-MASH1/Achaete-scute homolog 1 antibody (ab38556). Sin embargo me confirman que parece ser todo correcto desde su punto de vista, y lamentablemente no tenemos ninguna otra sugerencia posible.

Si os parece en el mismo envío que os haga del anticuerpo ab119776 (Anti-Hes1) puedo además mandaros otro anti MASH1 testado en IHC-P, como última alternativa para poder visualizar la proteína en vuestros tejidos.


Confírmamelo y realizo el pedido de inmediato. Espero tu respuesta.

Gracias por contactarnos de nuevo.

Lamento mucho que sigas teniendo problemas con dos de los anticuerpos enviados, y te agradezco que nos hayas enviado las imágenes.

En relación al MASH1, me temo que no puedo ofrecerte más recomendaciones a la hora de usarlo, puesto que en el laboratorio no se ha validado en secciones de parafina. Es posible de hecho que el anticuerpo no reconozca la proteína en estas condiciones. Al ser un policlonal, hay bastante variación de unos lotes a otros, y puede que a pesar de que en el pasado a otro usuario le funcionara en IHC-P, este nuevo lote no lo haga. En cualquier caso, no puedo asegurártelo puesto que no se testa en el laboratorio en esta aplicación.

Puedes, si tienes oportunidad, teñir un control positivo (carcinoma de mama o tejido de pulmón de ratón) o usarlo en otra aplicación validada (ICC, WB o IHC-FoFr) para comprobar su funcionamiento.

Respecto al anticuerpo contra Hes1 podemos echar un vistazo al protocolo seguido e intentar darte alguna sugerencia que pueda optimizar el resultado.

Muchas gracias por tu colaboración. Espero tu respuesta.
