前処理および保存

  • 保存方法および安定性

    Shipped at 4°C. Store at -20°C. Store under desiccating conditions.

    This product is an active protein and may elicit a biological response in vivo, handle with caution.

  • 再構成
    Reconstitute in 5-10 mM HCl to a concentration of 1.0 mg/ml. The solution can then be diluted to other aqueous buffers. Upon reconstitution ab123768 should be stored at 4°C for 2-7 days. For long-term storage, it is recommended to add a carrier protein (0.1% HSA or BSA) and store aliquots at –20°C or –70°C. Avoid freeze-thaw cycles.

  • 機能
    Insulin decreases blood glucose concentration. It increases cell permeability to monosaccharides, amino acids and fatty acids. It accelerates glycolysis, the pentose phosphate cycle, and glycogen synthesis in liver.
  • 関連疾患
    Defects in INS are the cause of familial hyperproinsulinemia (FHPRI) [MIM:176730].
    Defects in INS are a cause of diabetes mellitus insulin-dependent type 2 (IDDM2) [MIM:125852]. IDDM2 is 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.
    Defects in INS are a cause of diabetes mellitus permanent neonatal (PNDM) [MIM:606176]. PNDM is a rare form of diabetes distinct from childhood-onset autoimmune diabetes mellitus type 1. It is characterized by insulin-requiring hyperglycemia that is diagnosed within the first months of life. Permanent neonatal diabetes requires lifelong therapy.
    Defects in INS are a cause of maturity-onset diabetes of the young type 10 (MODY10) [MIM:613370]. MODY10 is a form of diabetes that is characterized by an autosomal dominant mode of inheritance, onset in childhood or early adulthood (usually before 25 years of age), a primary defect in insulin secretion and frequent insulin-independence at the beginning of the disease.

Application
ELISA
The human insulin protein (ab123768) was used in a sandwich ELISA from 250 ng/ml down to 3.9 ng/ml using the D6C4 anti insulin+proinsulin mouse capture antibody (ab8304) and the D3E7 -biotinylated anti Insulin+pro insulin mouse detection antibody (ab20756).
The human insulin standard was detected by the mouse antibody set described above.

Application
ELISA
Sandwich ELISA was set up using human purified insulin for standard curve, set up from 1.5μg/mL protein in a 1:2 serial dilution. Ab14042 used at 2μg/mL as capture antibody and Ab6995 used at 1:50 in a 1:4 serial dilution used for the detection antibody. Anti-mouse HRP conjugated secondary antibody used at 1:20,000.
