IPTG (isopropyl beta-D-thiogalactoside) Inducer for Beta-Galactosidase Expression acts as a molecular mimic of a lactose metabolite. The presence of IPTG triggers the activation of the lac operon for downstream gene transcription due to its binding the lac repressor. Due to the presence of a sulfur atom in IPTG, the cells cannot degrade the inducer and therefore its concentration remains constant. IPTG (isopropyl beta-D-thiogalactoside) Inducer for Beta-Galactosidase Expression is ideal for investigators in Immunology, Cell Biology, and Microbiology research.
Lysis Buffer is used to lyse cells under nondenaturing conditions. Cell Lysis Buffer is ideal to assist in Immunoprecipitation which allows for the purification by immunoprecipitation of recombinant proteins containing an epitope tag provided by the user. The user is able to further characterize the resultant purified protein by size, post-translational modification, western blot and other assays.
Formaldehyde can be utilized for both reversible and irreversible fixation of tissues by cross-linking of amino groups to nitrogen atoms of other proximal proteins or DNA. Formaldehyde can be utilized in ChIP experiments as well as a denaturant for RNA (preventing RNA folding to secondary structures). This fixative is designed for fixing tissue samples to be used in microscopy or histology.
PAP PEN is intended to provide a hydrophobic barrier when a circle is drawn around a specimen on the glass slide. Before use, hold the pen point up and press it with fingertip to take blocked air out from the pen barrel to prevent overflow. To start, press the tip of the pen straight down until fluid starts soaking the tip and then draw the circle around the specimen. Be sure to close the cap after use. Perform the dyeing work after the ink has dried well. If too much ink comes out, wipe it off.
