Features & Benefits
EliKine™ Human Prolactin ELISA Kit has high sensitivity and excellent specificity for detection of Human Prolactin. No significant cross-reactivity or interference between Human Prolactin and analogues was observed.
Background
Prolactin (gene name PRL) is a secreted neuroendocrine pituitary hormone that acts primarily on the mammary gland to promote lactation, but has pleiotropic effects in both males and females. Prolactin is predominantly found as 199 amino acid, 25 kDa glycosylated and 23 kDa non-glycosylated monomers. Human prolactin shares only 60% and 63% amino acid sequence identity with mouse and rat prolactin, respectively, although rat prolactin can activate the human prolactin recepto. Although better characterized in rodents than humans, post-translational modifcations such as polymerization, glycosylation, and proteolytic cleavage can alter the activities of prolactin. Non-glycosylated prolactin is produced by the pituitary gland and packaged in storage granules before secretion. Glycosylated prolactin is reported to be constitutively secreted, have lower biological potency, and be removed from the circulation more quickly.
This Human Prolactin ELISA kit is validated for use with Serum, Plasma, Other biological fluids. Samples should be collected, processed, and stored correctly to preserve analyte integrity — avoid repeated freeze-thaw cycles and centrifuge to remove particulates before use. Dilute samples exceeding the kit's detection range using the supplied assay diluent. Hemolytic, icteric, or lipemic samples may affect assay performance and should be tested with caution.
This is a sandwich ELISA kit employing an HRP (horseradish peroxidase)-conjugated secondary antibody paired with a TMB (3,3′,5,5′-tetramethylbenzidine) colorimetric substrate. In the sandwich format, the target analyte Human Prolactin captured on the microplate surface is detected by the conjugated antibody, generating a colorimetric signal proportional to analyte concentration. The reaction is stopped and absorbance measured at 450 nm on a standard microplate reader.
The complete protocol, from sample addition to final plate reading, requires approximately 3–5 hours. This includes two incubation periods (analyte binding and detection antibody steps), intermediate wash cycles to remove unbound material, 15–30 minutes of TMB substrate development, and final stop-solution addition before absorbance reading. Exact timing will vary with experience level and the number of samples processed in parallel.
Required equipment: (1) a microplate spectrophotometer capable of reading absorbance at 450 nm (reference wavelength 540–570 nm recommended for background correction); (2) precision single-channel or multichannel pipettes; (3) a plate washer or multichannel aspirator; (4) a microcentrifuge for sample clarification; and (5) a 37°C incubator or stable room-temperature environment. No fluorescence or luminescence reader is required — standard colorimetric plate readers are fully compatible with this kit.
This ELISA kit is formally validated for Human. Cross-reactivity with species not listed in the specification has not been independently characterized. Variability in protein sequence homology across species means that performance in unlisted species cannot be guaranteed without additional validation. For cross-species detection requirements or non-standard sample matrices, please contact BioHippo support or refer to the manufacturer's technical team for guidance.
