Total Prostate Specific Antigen (tPSA) IQ-ELISA Kit

Catalog No. ABIN6730847

Product Details

Target: Total Prostate Specific Antigen (tPSA)

Reactivity: Human

Detection Method: qPCR

Method Type: DNA-Binding ELISA

Detection Range: 0.16 pg/mL - 2500 pg/mL

Minimum Detection Limit: 0.16 pg/mL

Application: ELISA

Purpose: Human Immunoquantitative (PCR-Based) PSA-total ELISA Kit for cell culture supernatants, plasma, and serum samples.

Sample Type: Cell Culture Supernatant, Plasma, Serum

Analytical Method: Quantitative

Sensitivity: 0.16 pg/mL

Characteristics: The Immuno Quantitative Enzyme Linked ImumunoSorbent Assay (IQELISA™) is an innovative new assay that combines the specificity and ease of use of an ELISA with the sensitivity of real-time PCR. This results in an assay that is simultaneously familiar and cutting edge and enables the use of lower sample volumes while also providing more sensitivity. The Human PSA-total IQELISA™ Kit is a modified ELISA assay with high sensitivity qPCR readout for the quantitative measurement of Human PSA-total in serum, plasma, and cell culture supernatants. This assay employs an antibody specific for Human PSA-total coated on a 96-well PCR plate. Standards and samples are pipetted into the wells and PSA-total present in a sample is bound to the wells by the immobilized antibody. The wells are washed and a detection affinity molecule is added to the plates. After washing away unbound detection affinity molecule, primers and a PCR master mix are added to the wells and data is collected using qPCR. Ct values obtained from the qPCR are then used to calculate the amount of antigen contained in each sample, where lower Ct values indicate a higher concentration of antigen.

Application Details

Application Notes: The Immuno-Quantitative ELISA (IQELISA) kits are an innovative assay platform that combines the specificity and ease of use of an ELISA with the sensitivity of real-time PCR. This results in an assay that is simultaneously familiar and cutting edge and enables the use of only 1/10th the sample volume while also providing 10x more sensitivity than a traditional ELISA.
