    ターゲット情報

    • 機能

      Receptor for a number of inflammatory CC-chemokines including MIP-1-alpha, MIP-1-beta and RANTES and subsequently transduces a signal by increasing the intracellular calcium ion level. May play a role in the control of granulocytic lineage proliferation or differentiation. Acts as a coreceptor (CD4 being the primary receptor) for HIV-1 R5 isolates.

    • 組織特異性

      Highly expressed in spleen, thymus, in the myeloid cell line THP-1, in the promyeloblastic cell line KG-1A and on CD4+ and CD8+ T-cells. Medium levels in peripheral blood leukocytes and in small intestine. Low levels in ovary and lung.

    • 関連疾患

      Genetic variation in CCR5 is associated with suseptibility to diabetes mellitus insulin-dependent type 22 (IDDM22) [MIM:612522]. A multifactorial disorder of glucose homeostasis that is characterized by susceptibility to ketoacidosis in the absence of insulin therapy. Clinical fetaures are polydipsia, polyphagia and polyuria which result from hyperglycemia-induced osmotic diuresis and secondary thirst. These derangements result in long-term complications that affect the eyes, kidneys, nerves, and blood vessels.

    • 配列類似性

      Belongs to the G-protein coupled receptor 1 family.

    • 翻訳後修飾

      Sulfated on at least 2 of the N-terminal tyrosines. Sulfation contributes to the efficiency of HIV-1 entry and is required for efficient binding of the chemokines, CCL3 and CCL4.
      O-glycosylated, but not N-glycosylated. Ser-6 appears to be the major site. Also sialylated glycans present which contribute to chemokine binding. Thr-16 and Ser-17 may also be glycosylated and, if so, with small moieties such as a T-antigen.
      Palmitoylation in the C-terminal is important for cell surface expression, and to a lesser extent, for HIV entry.
      Phosphorylation on serine residues in the C-terminal is stimulated by binding CC chemokines especially by APO-RANTES.

      Question

      Dear Abcam Support,
      Our order number: MDS 614616

      The Anti-CCR5 antibody arrived 22-03-2012. As recommended, the tube containing the antibody was centrifuged and then aliquoted into 5 ul aliquots.
      We were expecting 100 ul, and therefore approximately twenty, 5 ul aliquots. On aliquoting, we obtained 15 aliquots - suggesting a total shipping volume of around 75-80ul. I have also checked the balance & the pipette - these are working within well within their limits. Up to the point of aliquoting, the antibody was stored at 4C.
      I will be grateful if you could look into this matter. I will also be grateful if you could sent us the shortfall.
      PS: We have also purchased an anti-CCR2 antibody, the number of aliquots obtained were in line with the protein concentration & amount of antibody, our order number for this was MDS 614615. The same pipette was used for aliquoting both the CCR2 & CCR5 antibodies.
      CC:
      Kindest regards,

      Question

      Predicted MW is 40 and papers have demonstrated that it could be as much as 40-45. Is abcam antibodty recognising correct sized band

      Read More
      Answer

      Thank you for your enquiry. I can confirm that ab1673 recognizes a band of approximately 40kDa. and that CCR5 has a predicted molecular weight of 40524Da. If you are continually obtaining a band of 37KDa may I suggest that you fill in our technical questionnaire. This will enable our technical team to better deal with your technical query and facilitate a quick resolution to your problem. I have added the technical questionnaire link for this antibody below. https://www.abcam.com/index.html?section=western&pageconfig=technical&intAbID=1673&mode=questionaire I hope this information helps, please do not hesitate to contact us if you need any more advice or information.

      Answer

      The image supplied shows a paraffin section of normal human spleen tissue. I suspect that the blocking step with the Sniper reagent may be a problem. Here is the protocol that we recommend. Immunohistochemistry on Paraffin sections: Paraffin sections of tissues fixed in 10% formalin are used. Preparation of slides: Place slides in 60 C oven overnight after cutting. Then follow the procedure below: 1) xylene 2x10min 2) 100% alcohol 2x10min 3) 95% alcohol 5 min 4) 80% alcohol 5 min 5) rinse in distilled water 2x2 min 6) antigen retrieval if necessary 7) Immunohistochemistry Antigen Retrieval: Sections were treated with antigen retrieval solution and steamed for 20 minutes followed by cooling for 20 minutes. Immunohistochemistry: Block the endogenous peroxide by incubating the sections with 3% H2O2 for 15 minutes at room temperature (RT). Wash the sections with PBS and incubate with 2% normal rabbit serum at room temperature to block the non-specific binding sites. Wash the section with PBS and incubate with primary antibody (anti-chemokine receptor) at recommended dilution for 60 minutes at RT. Wash the slides and incubate at RT with biotinylated rabbit anti-goat IgG H+L at 1-200 dilution for 30 minutes. Wash the slides and incubate with HRP-Streptavidin 1:400 dilution for 30 minutes. Wash the slides and incubate with DAB for 5-7 minutes at RT. Wash slides with PBS and counter stain with hematoxylin. I hope that this information is helpful. Please contact me if you have any futher questions or concerns.

      Question

      Thank you again. We are going to try to use ABC method and Tris Buffer next time. We also have Vectastain Universal Quick Kit. They say 0.3% H2O2 in methanol for 30 minutes. Should we use your recommended 1.6% H2O2 in TBS? And which is better to use ABC methods or Universal Immno-enzyme Polymer (UIP) methods? Please let us know.

      Answer

      Thank you for your email. I'm not familiar with the universal immunoenzyme polymer method and so I cannot comment as to how it compares with the ABC method. As you are using the Vectastain Universal Quick Kit, I do suggest following their suggestions. Please contact us again if you have any additional questions.

      Answer

      Thank you for the details that you have provided. I have a few more questions for you that will help me to troubleshoot this problem: 1. I was unable to open the attachments that you sent along with your email. You mentioned in your email that "All cells of both section were no stained." Does that mean that you are not seeing any staining at all with this antibody? 2. What dilutions of ab1673 have you tried? It is recommended to use ab1673 at a dilution of 1:300 in IHC-P. 3. Have you done a positive control? Ab1673 was tested and characterized for IHC using paraffin sections of human spleen, which is recommended as a positive control. 4. What was the batch number that you received (it is located on the vial)? Also, did you order directly from Abcam or through one of our distributors? Thank you again, and I look forward to hearing from you.
