Gel Electrophoresis Buffers and Diluents
Bioworld Carbonate Buffer, 0.5M, pH 9.0, 500 mL
Product DescriptionCarbonate buffer has a concentration of 0.5M and a pH at 9.0. The pH is determined by the ratio of acid to salt. Carbonate buffering system is important in different cellular processes such as its use to maintain the pH level of mammalian blood, the formation of acid in the lumen of the stomach, and to neutralize the pH of the chyme.For laboratory use only. Not fit for agricultural, household, clinical use or human consumption.
Bioworld Ammonium Bicarbonate Buffer 50 mM, pH 7.4, Sterile
Ammonium Bicarbonate Buffer 50 mM, pH 7.4, Sterileliquid, molecular biology grade, >99%, 50 mm, ph 7.4
Bioworld Citrate Buffer, 0.5M, pH 2.5, 500 mL
Product DescriptionCitrate buffer solution has a 0.5M concentration at a pH of 2.5. Citrate is used as an anticoagulant, a biological buffer, and is often prepared for antigen retrieval of tissue samples. The solution is designed to break protein cross-links, unmasking antigens and epitopes in formalin-fixed and paraffin embedded tissue sections, resulting in enhanced stain intensity of antibodies. Citrate has as a calcium chelator that forms complexes to disrupt the tendency of blood to clot.For laboratory use only. Not fit for agricultural, household, clinical use or human consumption.
Bioworld Citrate-Buffered Saline (20X), 1 L
Product DescriptionCitrate-buffered saline has a 20X concentration and is composed of 300 mM sodium citrate, 3M sodium chloride, and is at a pH of 7.0. As a conjugate base of a weak acid, citrate can act as a buffering agent or acidity regulator, resisting changes in pH. It is used for nucleic acid hybridization, blot transfer procedures and nucleic acid preparation.For laboratory use only. Not fit for agricultural, household, clinical use or human consumption.
Electron Microscopy Sciences Sym-Collidine, Reagent, pH 7.4 100 ML
(2,4,6-Collidine; 2,4,6-Trimethylpyridine)
CAS #108-75-8 (C₅H₂N)(CH₃)₃ F.W. 121.18
Assay: 99%
Sym-Collidine is used in combination with osmium tetroxide to provide excellent fixation and stable buffering. Since the pH does not change when distilled water or osmium tetroxide solution is added, isotonic or hyper-tonic solutions can be made without recoursing the other solutes. Tissues treated with Sym-Collidine have an excellent, uniform consistency. Uranyl acetate stains very well and lead stain is not too intense.
The buffers are prepared fresh for each order and conveniently packaged. Desired pH should be specified when ordering.

Alkali Scientific Orange G Loading Dye 6X Solution, 50 Milliliters
Orange G Loading Dye 6X Solution is a versatile dye used for loading samples in protein gel electrophoresis. The 6X concentration ensures that only a small volume of the dye is needed, minimizing dilution of the sample. This loading dye contains Orange G, which provides an easily visible color for monitoring sample migration during electrophoresis. Typically used for SDS-PAGE, the dye enhances the visibility of proteins as they enter the gel. With a volume of 50 milliliters, this solution is ideal for use in routine electrophoresis procedures, ensuring consistent sample loading and ease of use in various laboratory applications.

Electron Microscopy Sciences Acetate Buffer, 0.2M, pH 3.6-5.6 500 ML
Acetic Acid and Sodium Acetate, 0.2M, pH range 3.6-5.6. Our buffers are ideal for maintaining a constant pH during fixation and have an ionic constitution to prevent the extraction of cellular components or the deposition of precipitates of fixative chemicals. The buffers are prepared fresh for each order and conveniently packaged. Desired pH should be specified when ordering.
pH: 3.6-5.6
Electron Microscopy Sciences Millonig's Phosphate Buffer, 0.2M, 7.4 pH 500 ML
The pH of this buffer is 7.4 (0.1M); the osmolarity is 440 mosmols, so this buffer is hypertonic to most body fluids. Millonig recommended to use this buffer for the fixation of very hydrated tissues with osmium tetroxide. For marine organisms, a higher concentration of sodium chloride (3%) is recommended. We supply it in a double strength (0.2M), pH 7.4. Dilution is needed before use.
