      Proteinase K is an endolytic protease that cleaves peptide bonds preferentially next to the carboxyl group of N-substituted hydrophobic aliphatic and aromatic amino acids. Proteinase K is classified as a serine protease and exhibits broad substrate specificity. It can hydrolyze keratin; hence the name. Proteinase K is used for the digestion of proteins on tissue sections as a pre-treatment to aid in the preparation of mRNA and its detection by in situ hybridisation methods using oligonucleotide probes.

    Answer



    I can confirm that the Proteinase K (ab64220) is provided at 0.2 mg/ml, this is 200 ug/ml proteinase K. This can be used directly or diluted further if neccessary.

    Asked on Sep 19 2012

    Answer

    Thank you for contacting us.

    The concentration of proteinase K is approximately 200 ug/ml. For the 10ug/ml working dilution that you said you want for in situ hybridization, you will need to dilute it 1/20.

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

    Question

    Hi Kate,

    Thank you for your response.

    I am not quite sure what you mean by ‘With regards to the proteinase K, that should be fine.’

    The customer would like help finding a suitable proteinase K.

    Are you able to help look with the information I have provided you before?

    Thanks again J

    Kind regards,

    Answer

    Thank you for your reply.

    In theory, the proteinase K could also be used in DNA preparation. However, please not that this has not been tested. This reagent is sold as an antigen retrieval buffer.

    I hope this will be helpful. If you have any further questions, please do not hesitate to contact us.

    Answer

    Thank you for contacting Abcam. I have inquired to the lab about the concentration of Proteinase K in this product and have been told it is w/v. This product may be used directly as an antigen retrieval system for IHC. Incubate for 5-7 minutes at room temperature. Rinse and proceed with the IHC protocol. I hope this information is helpful. Please let me know if you have any questions.

    Question

    Dear Madam / Sir, IHC protocol in https://www.abcam.com/ps/pdf/protocols/ihc_p.pdf link have some absent information. In the document; When it is mention about enzymatic retrieval, it is written "for pepsin and proteinase K, see Section G" But, in the section isn't include these recipes. By the way, we would like to suggest Proteinase K (ab64220) to a customer. But we need its IHC application information: what is recommended Proteinase K concentration for IHC generally?

    Asked on Jan 25 2012

    Answer

    Thank you for contacting us.

    Thank you for making us aware of the oversight in the IHC handbook. I have been searching through our recommended protocols for antigen retrieval using Proteinase K but have not found an Abcam recommendation for the appropriate concentration. I have found been able to find other sites recommending a 20ug/ml solution and would recommend that you suggest that level to the customer. I have included a link below:

    http://www.ihcworld.com/_protocols/epitope_retrieval/proteinase-k.htm

    I also have sent a request for more information about the concentration/units of Proteinase K in ab64220 and will contact you as soon as I hear back from the lab.


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

    Asked on Dec 07 2011

    Answer

    Thank you for your enquiry. The number of tests that can be done with the 4 ml of proteinase K provided depends on the customers own procedure.  It is provided ready to use, and will not require diluting. If you are using this for antigen retrieval on slides, then the number of tests you can do will depend on how much you put on each slide. For example, if you put 100 ul on each slide, then you would be able to do 40 tests with 4 mls. I hope this will be helpful to you. If you have any further questions, please do not hesitate to contact us.
