  • RelevanceNeurophysin 1 specifically binds oxytocin. Oxytocin causes contraction of the smooth muscle of the uterus and of the mammary gland. Oxytocin is a posterior pituitary hormone which is synthesized as an inactive precursor in the hypothalamus along with its carrier protein neurophysin I. Together with neurophysin, it is packaged into neurosecretory vesicles and transported axonally to the nerve endings in the neurohypophysis, where it is either stored or secreted into the bloodstream. Oxytocin contracts smooth muscle during parturition and lactation. It is also involved in cognition, tolerance, adaptation and complex sexual and maternal behaviour, as well as in the regulation of water excretion and cardiovascular functions.

    Goat polyclonal to Rabbit IgG - H&L - Pre-Adsorbed (HRP) (ab65484) at 1/3000 dilution (Goat polyclonal to Rabbit IgG - H&L - Pre-Adsorbed (HRP) )
    developed using the ECL technique

    Performed under reducing conditions.

    Predicted band size : 12 kDa
    Observed band size : 12 kDa
    Additional bands at : 10 kDa (possible cleavage fragment).
    We hypothesize that the 12 and 10 kDa bands represent the pro and mature form of Oxytocin, respectively.
  • ICC/IF image of ab67457 stained HeLa cells. The cells were 4% formaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody ab67457 at 5µg/ml overnight at +4°C. The secondary antibody (green) was DyLight® 488 goat anti- rabbit (ab96899) IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.

Thank you for your inquiry.

You are correct that the mature Oxytoxin (CYIQNCPLG)is a nonapeptide and too short to analyse on a WB.

I can confirm that ab67457 recognises the prepropeptide of oxytoxin, also known as Oxytocin-neurophys...
