Life Science Buffers

Balanced salt solutions and powders used for molecular, protein, nucleic acid, and cell biology applications including cell culture, electrophoresis, ELISA, and chromatography processes; available in a variety of formulations and grades.

Buffer solutions serve to keep pH (acidity or alkalinity) nearly constant in a variety of chemical and biological applications. For example, a bicarbonate buffer helps maintain the pH of blood, a buffered saline maintains cellular contents at a consistent pH level, and buffers help maintain a narrow pH range for enzymes to function correctly.

Most biological samples used in research are kept at a pH of about 7.4. Common biological buffers used for tissue culture include Dulbeccos phosphate buffered saline (PBS), Tris base, HEPES, MOPS, PIPES, and other formulations developed for specific cell lines or applications. Most buffers used in cell culture are also DNase-, RNase-, and protease-free.

The choice of buffer for a particular biological reaction or site depends on several factors:

Temperature
Desired or target pH
Buffer toxicity (to the system)
Buffer interactions with other system components

ILEX LIFE SCIENCES LLC Promed Bioscience Atelocollagen Ultrapure, Porcine Type I, Enzymatic extraction, dialyzed, lyophilized, 10 mg

Atelocollagen Ultrapure, Porcine Type I, Enzymatic Extraction, Dialyzed, Lyophilized. Characterized by rich and ultra dialysis-purified Type I collagen content in a regular fibril-like configuration that retains its superior functionality and structural properties. The proprietary pepsin enzyme-based extraction removes telopeptides at the nonhelical N and C termini, resulting in a triple helix configuration that exhibits reduced immunogenicity. APPLICATION: Biocompatible and biodegradable, suitable for many research applications, such as bioink for 3D bioprinting, in vitro cell culture, cell functional assays, etc. MANUFACTURER: Promed Bioscience Ltd. CAS NO.: 9007-34-5. PURITY: greater than 97%. SOURCE: Porcine tendon. AMINO ACID ANALYSIS: Typical profile. STERILITY TESTING: Pass (0 cfu/g). STERILIZATION METHOD: Produced under strict aseptic conditions. CELL ATTACHMENT ASSAY: Pass. CELL TOXICITY ASSAY: Pass. OTHER NAMES: Type 1 Collagen, Collagen-1.
