Buffers & Concentrates

The Cell Stimulation and Protein Transport Inhibitor Cocktail is a pre-mixed cocktail used to induce cytokine production and inhibit their intracellular transport for flow cytometry detection. The solution is composed of an optimized mixture of brefeldin A, ionomycin, monensin, and PMA. PMA and ionomycin induce cytokine production in many cell types and brefeldin A and monensin are protein transport inhibitors.

Red Blood Cell Lysing Buffer, containing ammonium chloride, is formulated to lyse RBC from human and murine samples while leaving the lymphocytes intact. This buffer, supplied at 10X dilution, should be diluted to 1X to produce the desired effect.

The permeabilization buffer can be used for intracellular staining of cytoplasmic and nuclear antigens. The buffer maintains cell permeability throughout the staining process. It has been formulated to reduce background non-specific staining and increase the specific fluorescence signal. The 10x concentrate solution should be diluted with distilled water to 1x prior to use.

The Transcription Factor Fixation/Permeabilization solution can be used with the relevant antibodies to stain for transcription factors such as Foxp3 and intranuclear staining of cytokines, chemokines, and nuclear proteins. The concentrated solution should be used with the Transcription Factor Fixation/Permeabilization Diluent (cat#92555-00) and Permeabilization Buffer (cat# 92110-00).

BG iMatrix 511 is a chemically defined, animal-free, and xeno-free laminin-511 E8 fragment. Laminin-511 is well known to bind to integrin α6ß1, which is located on the cell surface and acts as a substrate for stem cell culture media for various cell types including ESCs and iPSCs. Recombinant laminin-511 E8 fragments are truncated, functional forms of laminin composed of the C-terminal regions of the alpha, beta, and gamma chains. Laminin-511 E8 (150 kDa) retains the full capability for binding to alpha 6 beta 1 integrin.</p> The 350ug size is supplied as 2x175ug vials. The 1050ug size is supplied as 6x175ug vials.    </p> <span style="font-size: small;">Review the <a title="Data Sheet" href="https://bio-gems.com/media/product_pdfs/ECMs/BG%20iMatrix-511.pdf" target="_blank" rel="noopener">Data Sheet</a> and <a title="Brochure" href="https://bio-gems.com/media/product_pdfs/ECMs/ECM_Marketing_Imatrix%20511_Imatrix%20511%20Silk_Brochure.pdf" target="_blank" rel="noopener">Product Brochure
