ターゲット情報

  • 機能

    Transferrins are iron binding transport proteins which can bind two Fe(3+) ions in association with the binding of an anion, usually bicarbonate. It is responsible for the transport of iron from sites of absorption and heme degradation to those of storage and utilization. Serum transferrin may also have a further role in stimulating cell proliferation.

  • 組織特異性

    Expressed by the liver and secreted in plasma.

  • 関連疾患

    Defects in TF are the cause of atransferrinemia (ATRAF) [MIM:209300]. Atransferrinemia is rare autosomal recessive disorder characterized by iron overload and hypochromic anemia.

  • 配列類似性

    Belongs to the transferrin family.
    Contains 2 transferrin-like domains.

    Question

    We wish to create a lateral flow assay, I am shopping for antibodies against human transferrin. Please help me on following questions.  1) Antibody pairing information to generate lateral flow test for detecting human transferrin  2) If such pairing information is available, we would like to know the performance of such pair in lateral flow test, i.e. the sensitivity and specificity   (crossreactivity with transferrin from other species).  3) Positive control information to validate the antibody performance in lateral flow test.

    Answer

    Lateral flow is not a tested application, however it is very much like sandwich ELISA so any ab pair used in sELISA should work in LF. We do offer a matched antibody for use with ab769 this is ab9538. Gold conjugation is generally used in LF. We do not carry gold conjugated anti-Transferrin, so the customer will need to conjugate one ab for use as the colored marker. 1) Ab9538 is tested and guaranteed in sELISA. For use in LT we recommend using this ab9583 as the test line and ab769 as colored particle. We do not have a gold conjugation kit however these may be found at online. Control line will be Mouse IgG1 monoclonal antibody [NCM1] - Isotype control (ab27479). You will need a detection system which will be able to read the gold particles, a flatbed scanner will likely work. 2) We do not test in LT. Ab769 is known to Reacts with: Rabbit, Human, Pig and not with Sheep, Horse, Cow, Dog or Carp. AB9538 is known to react with human and Marmoset; other species have not been tested. 3) Transferrin protein (Active) ab83560 has been tested with and is the positive control for sELISA with this pair.

    Question

    Customer kindly contacted us regarding the molecular weight of ab116604, ab129194, ab769.

    Answer

    Thank you for contacting Abcam.

    Since all three antibodies have IgG (or a IgG subclass) isotypes, the molecular weight of each is approximately 160kDa (23-25kDa for both light chains, and 53kDa for both heavy chains).

    Question

    Here are the additional information for which you asked : 1) Is your plasma sample from human (please specify species)? *Yes* 2) How long has ab769 been stored at 4C? The storage instructions are: Store at +4°C short term (1-2 weeks). Aliquot and store at -20°C or -80°C. Avoid repeated freeze / thaw cycles 4) *2 weeks* 3) How did you block your membrane - please specify blocking agent (and %) and blocking time? *Milk 10%* Could you also provide the purchase order number for this product = *192677* You will also find below the history of our prehundred e-mails where all this information was dejà mentioned ! Bests regards

    Answer

    Thank you for the requested information. I have re-examined our record and I was not able to find this information in our past correspondences with you. In regards to the purchase order number "192677", this was an order for ab7355 (Acinus antibody) placed by Patricia from the Inserm. Could you please check this information again and provide the correct PO# for ab769? Our policy at Abcam is that if an antibody does not work as specified on the datasheet, we will offer a replacement or reimbursement if the product has been purchased within 90 days. Again, I apologize for any inconveniences and I look forward to your reply.
