You Searched For: Assay Buffers

Assay buffers are mixtures of buffers, salts, detergents, protein, preservatives, and coloring agents. These buffers are used in ELISA assays for dilution of standards, samples, and reagents, and for blocking of non-specific interactions. Buffers may be used individually or in combination, Buffers may be used individually or in combination. Blocking buffers are specifically designed to preserve the conformational spatial arrangement of proteins in their native folded state, ensuring the biological activity of the protein.

Calcium Buffers

Catalog Number: (77664-082)
Supplier: WORLD PRECISION INSTRUMENTS LLC
Description: CALBUF-2 is especially suitable for calibrating fluorescent Ca⁺⁺ indicators. It provides eleven buffer standards in the 10⁻⁴ to 10⁻⁸ M Ca⁺⁺ range, whereas other commonly used fluorescent Ca⁺⁺ indicators have the apparent Kd in the range of 100 to 300 nM. As with any ionic sensitive indicator, the sensitivity range of these indicators is about 1.0 log unit above and below the Kd. CALBUF-2 provides seven calibration points in this sensitivity range. It has an osmolarity of 0.305, which is isotonic with most mammalian cells.
