Castor oil is a triglyceride obtained from Ricinus communis. It has been used to study its impact on rat lens condition.Castor oilnhas also been used as a test reagent for studying the dose-response relationship and mechanism of action of Saccharomyces boulardii by utilizing the rat model of castor oil-induced diarrhea. Packaging 1 L in glass bottle 250 mL in glass bottle
Immobilon ® ECL Ultra Western HRP Substrate is an ultra-sensitive reagent with long signal duration for the detection of horseradish peroxidase (HRP)-labeled antibodies on western blots. The intense signal created permits sensitive detection at the mid-to-low femtogram range using x-ray film or digital imaging systems.
For fast, reproducible and gentle extraction of active proteins from yeast and plant cells, use YeastBuster™ Protein Extraction Reagent. This reagent avoids the harsh conditions of vigorous mechanical or chemical treatment that often result in degradation of target proteins. Harvest cells and resuspend in YeastBuster™ protein extraction reagent, incubate for 15 minutes and then remove cell debris by centrifugation. Your extra…
Coupling TLC plates with mass spectrometry (TLC-MS) is a new field of high interest in planar chromatography. One particular advantage of TLC-MS is the flexibility it offers in the choice of mobile phases for separations. In comparison, HPLC-MS coupling does not allow the use of certain mobile phases, such as inorganic buffers.
The reagents for sample preparation have an important impact on the outcome of the measurement. In modern instrumental trace analysis, any impurity can disturb the measurement so acids with low impurities should be used to minimize the interference on the instrument signal. High purity Suprapur ® acids offer the most suitable purity of wet digestion materials with low impurities during the entire minimum shelf life.
BL21(DE3) is a chemically competent E. coli cell suitable for transformation and high level protein expression using a T7 RNA polymerase-IPTG induction system.
Non-sterile goat serum collected from normal healthy goats. Used for blocking of interfering antibodies.
