Material not included: Microplate Reader capable of reading absorbance at 450nm. Incubator. Automated plate washer (optional). Pipettes and pipette tips capable of precisely dispensing 0.5 μL through 1 mL volumes of aqueous solutions. Multichannel pipettes are recommended for large amount of samples. Deionized or distilled water. 500 mL graduated cylinders. Test tubes for dilution.

Application Details

Application Notes: Before using Kit, spin tubes and bring down all components to bottom of tube. Duplicate well assay was recommended for both standard and sample testing.

Sample Volume: 100 μL

Plate: Pre-coated

Protocol: ELISA Kit is based on standard sandwich enzyme-linked immune-sorbent assay technology. An antibody has been precoated onto 96-well plates. Standards and test samples are added to the wells, a biotinylated detection antibody specific for target is added subsequently and then followed by washing with PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex was added and unbound conjugates were washed away with PBS or TBS buffer. HRP substrate TMB was used to visualize HRP enzymatic reaction. TMB was catalyzed by HRP to produce a blue color product that changed into yellow after adding acidic stop solution. The density of yellow is proportional to the target amount in sample captured in plate.

Target Details for Midkine

Target: Midkine (MDK) (Midkine (Neurite Growth-Promoting Factor 2) (MDK))

Alternative Name: Mdk

Background:

Background: Midkine (MK) is a member of a family of neurotrophic and developmentally-regulated heparin-binding molecules that currently consists of midkine, pleiotrophin/PTN and avian RI-HB. This gene is mapped to 3q24. Across species, MK shows 87 % amino acid identity between the human and mouse proteins. Between family members, human MK is approximately 50 % identical to human PTN.

Gene Full Name: midkine
