Acidicase™ Peptone Gibco™

Acidicase Peptone is a hydrochloric acid hydrolysate of casein. The manufacturing process produces a casein hydrolysate, which has a high salt content of approximately 37% and nitrogen content of approximately 8%. The hydrolysis of the casein, a milk protein rich in amino acid nitrogen, is carried out until all the nitrogen is converted to amino acids or other compounds of relative simplicity. Casein contains little cystine and is deficient in tryptophan, which is destroyed by the acid treatment.

Features:
• Hydrochloric acid hydrolysate of casein
• Animal origin (AO) nutritional supplement
• Milk protein rich in amino acid nitrogen

Applications of Acidicase Peptone include:
• Intended for use as a nutritional supplement in vitamin assays, susceptibility testing, and other laboratory media and microbial fermentation in which the high salt content will not interfere

GlutaMAX™ Supplement Thermo Scientific™

Gibco® GlutaMAX™ Supplement is an alternative to L-glutamine, with increased stability that improves cell health. GlutaMAX™ Supplement is suitable for both adherent and suspension culture of mammalian cells, with no adaptation required. GlutaMAX™ Supplement is offered as a 200 mM L-alanyl-L-glutamine dipeptide in 0.85% NaCl. GlutaMAX™ Supplement is also included in a variety of media formulations. Compared to L-glutamine, GlutaMAX™ Supplement:

Features:

Minimizes toxic ammonia build-up
Improves cell viability and growth
Remains stable across a wide range of temperatures

Minimizes toxic ammonia build-up
Unlike L-glutamine, GlutaMAX™ Supplement does not spontaneously break down to form ammonia. Instead, cells cleave the dipeptide bond to release L-glutamine as needed. This system prevents waste build-up and maintains a fresh supply of L-glutamine during long-term culture.

Improves cell viability and growth
Cultures with lower levels of ammonia show improved cell viability. In addition, culture conditions are more controlled due to the consistent concentration of GlutaMAX™ Supplement that is not possible with L-glutamine.

Remains stable across a wide range of temperatures
GlutaMAX™ Supplement is room-temperature stable and ready to use. GlutaMAX™ Supplement retains full functionality for 24 months at room temperature, 2 to 8°C, or -5 to -30°C for convenient storage and handling. GlutaMAX™ Supplement is even stable at 37°C for a week or more.

Ampicillin, sodium salt, irradiated Gibco™

Ampicillin is an antibiotic in the broad-spectrum penicillin group. Ampicillin differs from penicillin only by the presence of an amino group, which facilitates penetration through the outer membrane of some gram-negative bacteria. Ampicillin acts by interfering directly with the turnover of the bacterial cell wall and indirectly by triggering the release of enzymes that further alter the cell wall.

Gibco Ampicillin is used as a selective antibiotic generally at a concentration of 20–125 µg/mL. Ampicillin selection is based on hydrolysis and inactivation of its beta-lactam ring by beta-lactamase expressed by the bla gene. Sometimes, beta-lactamase produced by the bacteria is secreted into the medium resulting in inactivation of ampicillin in the culture medium. Ampicillin degradation on agar plates can lead to the formation of satellite colonies. Growth of these colonies can be halted by adding fresh ampicillin. To avoid beta-lactamase buildup, special care must be taken while handling cultures and determining the correct dose of antibiotic.

Ampicillin antibiotic in powder form is an economical choice that can be used in a wide range of gram-positive and gram-negative infections. This product is provided as a powder and should be made into a stock solution at a concentration of 10 mg/mL in water.

Staphylococcus aureus (Wood strain without protein A) BioParticles™, fluorescein conjugate Invitrogen™

The Molecular Probes® BioParticles® product line consists of a series of fluorescently labeled, heat- or chemically killed bacteria and yeast in a variety of sizes, shapes, and natural antigenicities. These fluorescent BioParticles® products have been employed to study phagocytosis by fluorescence microscopy, quantitative spectrofluorometry, and flow cytometry.

We offer E. coli (K-12 strain), S. aureus (Wood strain, without protein A) and zymosan (S. cerevisiae) BioParticles® conjugates covalently labeled with a variety of different fluorophores (special care has been taken to remove free dye after conjugation). Unlike the fluorescence of fluorescein-labeled BioParticles® conjugates, which is partially quenched in acidic environments, the fluorescence of the Alexa Fluor®, BODIPY® FL, tetramethylrhodamine and Texas Red® dye conjugates is uniformly intense over the pH range from 3 to 10.

BioParticles Specifications:
• Label (Ex/Em): Fluorescein (~494/518 nm)
• Particle: S. aureus (Wood strain, without protein A)
Opsonizing reagent available


Using BioParticles Products
BioParticles® conjugates are provided as lyophilized powders. There are approximately 3 x 108 E. coli or S. aureus particles per mg solid and approximately 2 x 107 zymosan particles per mg solid. BioParticles® conjugates can be reconstituted in the buffer of your choice for use in phagocytosis assays. The fluorescence of BioParticles® conjugates that are bound to the surface of the cell (but not internalized) can be quenched by ethidium bromide, trypan blue, or other quenchers. In addition to cellular applications, fluorescent BioParticles® conjugates may be effective as flow cytometry calibration references when sorting bacteria and yeast mutants. These small particles may also be useful references for light scattering studies because their sizes and shapes differ in characteristic ways.

Find More BioParticles® Products
We offer a large range of dye-labeled and unlabeled E. coli (K-12 strain), S. aureus (Wood strain, without protein A), and zymosan (S. cerevisiae) BioParticles® products.
