靶标

  • 功能

    Ligand for members of the frizzled family of seven transmembrane receptors. Probable developmental protein. Signaling by Wnt-7a allows sexually dimorphic development of the mullerian ducts.

  • 组织特异性

    Expression is restricted to placenta, kidney, testis, uterus, fetal lung, and fetal and adult brain.

  • 疾病相关

    Defects in WNT7A are the cause of limb/pelvis-hypoplasia/aplasia syndrome (LPHAS) [MIM:276820]; also known as absence of ulna and fibula with severe limb deficiency. LPHAS is a limb-malformation disorder characterized by various degrees of limb aplasia/hypoplasia and joint dysplasia.
    Defects in WNT7A are a cause of Fuhrmann syndrome (FUHRS) [MIM:228930]; also known as fibular aplasia or hypoplasia femoral bowing and poly- syn- and oligodactyly. Fuhrmann syndrome is a distinct limb-malformation disorder characterized also by various degrees of limb aplasia/hypoplasia and joint dysplasia.

Question

Dear
Thanks for your kindly reply, after contacting with this customer and passed these suggestions to him, then he modified his experiment step as your suggestion, but it didn’t improve his results, he also indicated he didn’t has any positive control can test in this experiment, and he said the band which at 48kDa will disappear after he reused this antibody, he offered the RT-PCR data to prove this protein will expression in this sample, please check it and help this customer to solve the problem.
Thanks for your kindly help

Best regards

Answer

Thank you for your reply.

I contacted with my lab colleagues who confirmed this lot has successfully passed our QC controls, and as with previous batches, it should be detecting a band at ˜40KDa, rather than 48KDa.

Please find attached one of the last blots obtained comparing our new batch (lane 1) with the batch you have tested (lane 3).

As you have mentioned, the band at ˜48KDa disappear when retesting the antibody, it may well be a non specific band. However, attending to the image sent on your first email, there is a weak band showing at ˜43 kDa that could be reduced by the milk blocking. I would therefore recommend you to use the same blocking agent used in our lab: 5%BSA, in an attempt to increase the target’s band intensity.

In any case, all of our products are covered by our Abpromise guarantee; which ensures that you can trust our products, and they should work in the tested species and applications stated on the datasheet, or we will offer a replacement, credit, or refund, if reported within 4 months of purchase.

I hope these tips help, thank you for your cooperation. Should the suggestions not improve the results, please do not hesitate to contact me again and I’ll be more than happy to help you further.

Answer

Thank you for taking the time to complete our questionnaire.

The predicted band size for this protein is 39KDa, however, attending at our in-house tests, the observed band size appears at approximately 41KDa, and other unknown additional bands are shown at lower molecular weights.

In order to identify the correct band for the protein I would suggest using a positive control. Human kidney tissue lysate has been proved to express this protein, and therefore could be used as such.

In an attempt to improve the results observed I would suggest increasing the percentage of milk to 5% as well as optimising the sample preparation lysing your tissue with RIPA buffer and adding phosphatase inhibitors.

I would also recommend decreasing the protein load to 20ug, and using less concentrate dilution of primary antibody (e.g. 1/1000).

I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.

Answer

Thank you for calling Abcam. I have done the alignment between the sequences you sent and the immunogen sequences for the antibodies we discussed. For DVL1, there is 75% match between the sequence you sent and the immunogen sequence used for ab106914. We normally look for a 85% similarity before we would recommended trying an antibody, so in this case I do not think the antibody will react with pig. For Wtn7a, there is a 100% match between your sequence and the immunogen sequence used for ab100792. Therefore I would be very confident that this antibody would recognize pig Wnt7a. Please let me know if there is anything else I can help you with.
