ターゲット情報

  • 機能
    Putative nuclease involved in innate immune response by acting as a negative regulator of the cell-intrinsic antiviral response. May play a role in mediating proinflammatory responses to TNF-alpha signaling.
  • 組織特異性
    Expressed in heart, skeletal muscle, spleen, liver, small intestine, placenta, lung and peripheral blood leukocytes. No expression is seen in brain and thymus.
  • 関連疾患
    Defects in SAMHD1 are the cause of Aicardi-Goutieres syndrome type 5 (AGS5) [MIM:612952]. A form of Aicardi-Goutieres syndrome, a genetically heterogeneous disease characterized by cerebral atrophy, leukoencephalopathy, intracranial calcifications, chronic cerebrospinal fluid (CSF) lymphocytosis, increased CSF alpha-interferon, and negative serologic investigations for common prenatal infection. Clinical features as thrombocytopenia, hepatosplenomegaly and elevated hepatic transaminases along with intermittent fever may erroneously suggest an infective process. Severe neurological dysfunctions manifest in infancy as progressive microcephaly, spasticity, dystonic posturing and profound psychomotor retardation. Death often occurs in early childhood.

    Lanes 1 - 3: Merged signal (red and green). Green - ab128107 observed at 70 kDa. Red - loading control, ab181602, observed at 37 kDa.

    ab128107 was shown to recognize SAMHD1 when SAMHD1 knockout samples were used, along with additional cross-reactive bands. Wild-type and SAMHD1 knockout samples were subjected to SDS-PAGE. ab128107 and ab181602 (loading control to GAPDH) were diluted 1/500 and 1/10 000 and incubated overnight at 4°C. Blots were developed with Goat anti-Mouse IgG H&L (IRDye® 800CW) preadsorbed (ab216772) and Goat Anti-Rabbit IgG H&L (IRDye® 680RD) preadsorbed (ab216777) secondary antibodies at 1/10 000 dilution for 1 h at room temperature before imaging.

Answer

Thank you for contacting us.
I am sorry to hear that the antibodies don't seem to work as expected.

As we discussed over the phone, the following protocols tips can help with improving your results:

1) loading more protein onto the gel (e.g. 20-30 ug or more if needed)
2) using more primary antibody (e.g. 1/500 per recommended dilutions on the datasheet)
3) check if the secondary antibody is working well with other primary antibodies

I hope these tips will be of help.
Please do not hesitate to contact us if you need any more advice or information.
