Anti-Mycoplasma Pneumoniae Rabbit Polyclonal Antibody

Catalog Number: (89363-070)

Supplier: Genetex

Description: Mycoplasma pneumoniae is a member of the class Mollicutes, meaning soft skin. Along with the other members of this class (Acholeplasma, Anaeroplasma, Asteroleplasma, Spiroplasma, and Ureaplasma) Mycoplasma are characterized by their unusually small genome as well as their complete lack of a bacterial cell wall. M. pneumoniae is a common cause of mild pneumonia and usually affects people younger than 40. Various studies suggest that it causes 15 to 50% of all pneumonia in adults and an even higher percentage of pneumonia in school aged children. Beta lactam antibiotics such as penicillin and cycloserine are ineffective as they act specifically to disrupt the cell wall so alternative antibiotic therapies such as the use of polyenes may be required. People at highest risk of mycoplasma pneumonia infection include those living or working in crowded areas such as schools and homeless shelters, although many people who become infected have no identifiable risk factor. M. pneumoniae can be detected via serology, PCR or in cell culture assays.

Amyl acetate 98, reagent suitable for use as excipient

Supplier: Spectrum Chemicals

Description: Amyl Acetate, Reagent, with an odor similar to bananas and apples, is often used as a flavoring agent. It can also be used as a solvent and as part of the preparation of penicillin. Its reagent grade means this is the highest quality commercially available for this chemical and that the American Chemical Society has not officially set any specifications for this material.

Ampicillin sodium salt, powder_white, Cell Culture grade

Supplier: MP Biomedicals

Description: Ampicillin sodium salt is a semi-synthetic derivative of penicillin, active as a broad-spectrum antibiotic. It is inactivated by beta-lactamases and for this reason a beta-lactamase inhibitor should be considered when using ampicillin. Against gram-positive bacteria, ampicillin has a similar mode of action as benzylpenicillin; against gram-negative bacteria, it has a similar mode of action as chloramphenicol and tetracyclines. In E. coli it inhibits cell wall synthesis.

Ampicillin, powder

Supplier: MP Biomedicals

Description: Ampicillin is a semi-synthetic derivative of penicillin, active as a broad-spectrum antibiotic which is used to select bacteria cells with specific resistance during general microbiology studies.

Cefotaxime sodium salt ≥95%, off-white powder

Supplier: MP Biomedicals

Description: Cefotaxime is a cephalosporin, which acts by interference of synthesis of peptidoglycan of the bacterial cell wall. Cefotaxime, a cephalosporin antibiotic, is active against both gram-negative and gram-positive bacteria. In addition, cefotaxime blocks the division of cyanobacteria and lower plant organelles/plastids such as the photosynthetic organelles of Glaucophytes and chloroplasts of bryophytes.
Cefotaxime is used for infections of the respiratory tract, skin, bones, joints, urogenital system, meninges, and bloodstream. It generally has good coverage against most Gram-negative bacteria, with the notable exception of Pseudomonas. It is also effective against most Gram-positive cocci except for Enterococcus. It is active against penicillin-resistant strains of Streptococcus pneumoniae. It has modest activity against the anaerobic Bacteroides fragilis. In meningitis, cefotaxime crosses the blood–brain barrier better than cefuroxime.
Cefotaxim inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs) which inhibits the final transpeptidation step of peptidoglycan synthesis in bacterial cell walls. As a result, bacteria lyse due to cell wall autolytic enzymes.

SDS

Cefmetazole sodium 921 µg/mg

Catalog Number: (10067-132)

Supplier: Thermo Scientific Chemicals

Description: Cefmetazole is used to study the effect of expression, binding, and inhibition of penicillin-binding proteins (with the exception of PBP2) on bacterial cell wall mucopeptide synthesis. It is also used to study protein mediated antibiotic transport.

Piperacillin sodium salt, white powder

Supplier: MP Biomedicals

Description: Piperacillin is a semisynthetic, broad-spectrum ureidopenicillin antibiotic. It is derived from ampicillin. Piperacillin inhibits the last stage of bacterial cell wall synthesis by binding to certain penicillin-binding proteins (PBPs), which results in cell lysis. Cell lysis is mediated by bacterial cell wall autolytic enzymes. Piperacillin may interfere with autolysin inhibitors.
It has been used in pharmacokinetic studies in order to optimize antimicrobial therapy in patients with sepsis. It is used to study piperacillin hypersensitivity reactions and to study multidrug-resistant organisms.

Ampicillin sodium salt

Supplier: MP Biomedicals

Description: Ampicillin is a semi-synthetic derivative of penicillin, active as a broad-spectrum antibiotic which is used to select for ampicillin resistance in mutated and transformed cells.
