ターゲット情報

  • 機能

    Binds to folate and reduced folic acid derivatives and mediates delivery of 5-methyltetrahydrofolate to the interior of cells.

  • 組織特異性

    Exclusively expressed in tissues of epithelial origin. Expression is increased in malignant tissues. Expressed in kidney, lung and cerebellum.

  • 関連疾患

    Defects in FOLR1 are the cause of neurodegeneration due to cerebral folate transport deficiency (NCFTD) [MIM:613068]. NCFTD is an autosomal recessive disorder resulting from brain-specific folate deficiency early in life. Onset is apparent in late infancy with severe developmental regression, movement disturbances, epilepsy, and leukodystrophy. Note=Recognition and diagnosis of this disorder is critical because folinic acid therapy can reverse the clinical symptoms and improve brain abnormalities and function.

  • 配列類似性

    Belongs to the folate receptor family.

  • 翻訳後修飾

    Eight disulfide bonds are present.
    The secreted form is derived from the membrane-bound form either by cleavage of the GPI anchor, or/and by proteolysis catalyzed by a metalloprotease.

  • 細胞内局在

    Question

    I have a question about your products the Anti-Folate Binding Protein antibody (ab2107) and the Anti-Folate Binding Protein antibody [LK26] (ab3361), I was wondering how many runs (approximately) would you get from each product? Please email me at your earliest convience.

    Read More
    Answer

    It will depend on how you want to use the antibody and how much is required for each test . I updated the ab2107 datasheet to show suggested dilution ranges for the applications that are listed on the datasheet.

    WB: 1/500 - 1/5000.
    IP: 1/100.
    ELISA: 1/5000 - 1/20000.

    Untested applications (that is, not listed on the datasheet) will require optimization tests but I can suggest a range of dilutions to try for those too.

    The ab3361 datasheet has suggestions for dilutions for IHC and western blotting but the other applications that are listed were added based on publications that did not specify the dilutions or concentrations that were used.

    Question

    Buenos dias,
    Nos parecebuena idea probar conotro anticuerpo. Vamos aprobar con la segunda opcion que nos recomiendas (ab125030).
    La dirección de envio es la misma que la del otro anticuerpo.
    Muchisimas gracias por vuestra ayuda,
    un saludo,

    Question

    Buenas tardes,
    Hemos cambiado las condiciones del western blott tal y como nos aconsejaste y seguimos sin tener resultados. Sin embargo hemos realizado una inmunocitoquímica en células de neuroblastoma y el anticuerpo ha marcado bien. No sabemoscuál puede ser el fallo. ¿que solución nos proponeis?
    Muchas gracias,

    Answer

    Gracias por tu respuesta.

    Si te parece puedo enviaros para que probéis un anticuerpo diferente contra la misma proteína.

    Echarle un vistazo a los otros productos que tenemos disponibles contra Folate Binding Protein validados en WB en células humanas:

    https://www.abcam.com/Folate-Binding-Protein-antibody-ab67422.html

    https://www.abcam.com/Folate-Binding-Protein-antibody-EPR4708-2-ab125030.html

    La última de las opciones corresponde a un rabbit monoclonal, que suelen dar muy buenos resultados, y muestras más especificidad y sensibilidad que los mouse monoclonales.

    Si os interesa, os envío este anticuerpo de forma gratuita puesto que el ab3361 se encuentra aun en garantía.

    Quedo a la espera de tu respuesta para ayudaros con este problema.

    Question

    Buenas tarde ,
    Adjunto el impreso. Espero que sirva de ayuda para poder solucionar el problema. No adjunto fotos porque las imagenes que salian al revelar el WB eran completamente negras con algo de ruido del secundario.
    un saludo,

    Answer

    Muchas gracias por mandarnos el cuestionario relleno.

    Para intentar optimizar los resultados del anticuerpo hay una serie de sugerencias que me gustaría hacer. De cualquier manera, al estar al anticuerpo bajo garantía en caso de que las sugerencias no consiguieran optimizar el protocolo, estaré encantada de ofreceros un reemplazo del mismo, o un vale sin caducidad si preferís.

    - Para extraer la proteína podéis probar NP-40 como buffer de lisis. Este buffer está indicado para estudiar proteínas membranales. Podéis echar un vistazo al protocolo online donde se detalla más la información de este y otros buffers:

    https://www.abcam.com/index.html?pageconfig=resource&rid=11379#A1

    - Usar un control positivo siempre ayuda a entender el problema ocurrido. Si tuvierais alguna de las siguientes líneas celulares disponibles: JAR, HeLa, MCF7, 293T y A549 podrían servir como control.

    - Usar un método de bloqueo menos agresivo, como por ejemplo 5% BSA durante 1 o 2 horas a TA (en ese caso los anticuerpos diluirlos en TBST únicamente, o 1% BSA en TBST).

    -Simplemente a modo de comprobación, chequear que tanto el secundario como el sustrato enzimático están en perfectas condiciones y dan el resultado esperado en otros sistemas.

    Os propongo que probéis estas variaciones en el protocolo y en caso de seguir sin obtener el resultado esperado me volváis a contactar. Si el anticuerpo resultara haber salido defectuoso, al estar en garantía, os mandaríamos un vial nuevo gratuito o un reembolso en compensación.

    Así pues, os deseo mucha suerte, y espero vuestra respuesta.

    Question

    I have purchased your ab3361 two months ago and it works well (on western blot which you do not indicate). However I wanted to know the subtype of folate receptor recognized by this antibody (alpha, beta or both).

    Read More
    Answer

    Thank you for your enquiry. Ab3361 was generated using gestational choriocarcinoma cell line, Lu-75, as the immunogen. However, we have not conducted testing to determine whether the antibody is specific for one or the other subtype of the receptor. I'm pleased to hear that the antibody worked well for you in WB as it has not previously been tested in that application. We would be very grateful for you if you could submit an Abreview via the product datasheet. We always encourage customers to feed their results back to us, whether positive or negative, and make all information about each of our products available to researchers. If you send us an Abreview, we can offer you 50 Abcam Points (a further 100 Abpoints will be offered for an image). To find out more about our Loyalty Scheme and Abpoints, please visit our website and look at Your Account panel (left bottom section on our home page) or the Abreviews section on the product datasheet. You can submit the Abreview if you click on the Abreview section (top menu bar) on the on-line datasheet of this antibody. It is a very straightforward process. Should you need any help how to submit an Abreview, then please do not hesitate to contact us again. Please contact us again if you have any additional questions.
