pH Paper and other Test Strips
Single-use test materials used to rapidly and semi-qualitatively determine the acidity or alkalinity of liquids or to measure another parameter or substance; may include tests for starch, chlorine, and molybdenum; usually via the use of color-based reactions.
pH Papers, pH strips, pH sticks, and pH test kits are used in laboratory, industrial, and educational environments to qualitatively assess pH levels or monitor acid-base titrations in a range of sample types.pH Buffer reference standards are used for the accurate calibration of pH meters and monitors for far more precise and quantitative pH measurement.
pH Test papers are supplied either as rolls, tear-off strips, or sticks. They are impregnated with indicator dyes that change color at a specific pH. In some products, indicator dyes are covalently linked to cellulose fibers to avoid bleed-out (leaching) and contamination of the test sample.
Some pH papers indicate simple acid or base conditions with a single red-to-blue color change (also called litmus papers). Universal pH papers and strips contain a combination of indicators that cover a range of pH values up to and including 0 to 14 in a single test. The observed color change is checked against a comparison chart supplied with the papers.
Alternatively, for metered assessments of pH, standard or reference pH buffers are used to calibrate pH meters and other electrochemical sensors.
Standard Buffer Characteristics:
• Typically supplied at fixed values of pH 4.01, pH 7.00, and pH 10.01
• May be color-coded for easy and quick identification
• Certified to their nominal pH and accuracy at a specified temperature (typically 20°C)
• Supplied as ready-to-use solutions or concentrates
• Contain antifungals for extended shelf life

Innovative Research Inc Dog Ttl PAI1 Kit
Canine Total PAI-1 ELISA Kit - Dog PAI-1 total assay is intended for the quantitative determination of total plasminogen activator inhibitor type 1 (PAI-1) in dog plasma. For research use only. Strip well format. Reagents for up to 96 tests. Dog PAI-1 present in plasma reacts with the capture antibody coated and dried on a microtiter plate. Free, latent, and complexed PAI-1 will bind to the plate. After appropriate washing steps, primary antibody binds to the captured protein. Excess primary antibody is washed away and bound antibody is reacted with horseradish peroxidase conjugated streptavidin. TMB substrate is used for color development at 450nm. A standard calibration curve is prepared along with the samples to be measured using dilutions of dog PAI-1. The amount of color development is directly proportional to the concentration of total PAI-1 in the sample.
Innovative Research Inc Ms Ttl A2Ap Kit
Mouse Total Alpha 2 Antiplasmin (A2Ap) ELISA Kit - This mouse Alpha 2-antiplasmin assay is for the quantitative determination of total Alpha2-antiplasmin in mouse plasma. For research use only. Strip well format. Reagents for up to 96 tests. Total mouse Alpha2-antiplasmin will bind to the affinity purified capture antibody coated on the microtiter plate. Complexed and free Alpha2-antiplasmin will react with the antibody on the plate. After appropriate washing steps, biotin labeled polyclonal anti-mouse Alpha2-antiplasmin primary antibody binds to the captured protein. Excess antibody is washed away and bound antibody is reacted with streptavidin conjugated to horseradish peroxidase. Following an additional washing step, TMB substrate is used for color development at 450nm. A standard calibration curve is prepared along with the samples to be measured using dilutions of mouse Alpha2 antiplasmin. Color development is proportional to the concentration of 2-antiplasmin in the samples.
