Anti-Human Prolactin

Purified Recombinant Human PRL (>98%)

This antigen affinity purified polyclonal antibody has been 0.2 µm filtered and lyophilized from modified Dulbecco’s phosphate buffered saline (1X PBS) pH 7.2 – 7.4 containing 5.0% w/v trehalose with no calcium, magnesium, or preservatives present.

Lyophilized

The lyophilized antigen affinity purified polyclonal antibody can be stored desiccated at -20°C to -70°C for twelve months from date of receipt. The reconstituted antibody can be stored for at least four weeks at 2-8°C. For long-term storage of the reconstituted antibody, aseptically aliquot into working volumes and store at -20°C to -70°C in a manual defrost freezer. Avoid Repeated Freeze Thaw Cycles. No detectable loss of activity was observed after six months.

Neutralization: This antibody is useful for neutralization of Human PRL bioactivity. The antibody dose required to neutralize 50% (ND₅₀) of the biological activity of Human PRL (at 0.5 ng/ml) is 0.02 - 0.05 µg/ml.
Immunohistochemistry: Suitable for use at concentration of 1-15 µg/mL.

Goat Anti-Human Prolactin (PRL) recognizes Human PRL. This antigen affinity purified polyclonal antibody was purified using a proprietary chromatographic technique that includes covalently immobilizing the antigen proteins or peptides to agarose based beads. This purification method enhances specificity, reduces nonspecific binding of extraneous IgG and provides you with the most reliable reagent available for your early discovery research.

Prolactin (PRL) or Luteotropic hormone (LTH) is best known as the pituitary modulator of lactation and reproduction.¹ Prolactin is a multifaceted hormone that is capable of modulating hundreds of physiological processes in adult vertebrates.² PRL promotes proliferation, survival and migration of cancer cells acting via the prolactin receptor (PRLR).³ It also modulates maternal behavior and mediates hypothalamic pituitary adrenal axis inhibition during lactation via PRL receptors in the brain.⁴ Prolactin also has a number of other effects including contributing to surfactant synthesis of the fetal lungs at the end of the pregnancy and immune tolerance of the fetus by the maternal organism during pregnancy. It also decreases normal levels of sex hormones — estrogen in women and testosterone in men.⁵
