Folic acid, also known as folate, is a B vitamin that can be found in a variety of fruits and vegetables. It can also be chemically synthesized. Folate, a watersoluble vitamin, helps the body form red blood cells and aids in the formation of genetic material within every body cell. This product exhibits metal binding properties. Hematopoietic vitamin present, free or combined with one or more additional molecules of L-(+)-glutamic acid, in liver, kidney, mushrooms, spinach, yeast, green leaves, and grasses.
Folic acid (Vitamin B9 and folate) is essential to numerous bodily functions. The human body needs folate to synthesize DNA, repair DNA, and methylate DNA as well as to act as a cofactor in certain biological reactions. It is especially important in aiding rapid cell division and growth, such as in infancy and pregnancy.
Folic acid (FA) and dihydrofolic acid (FAH2) are substrates of dihydrofolate reductase(s) which reduce them to tetrahydrofolate (THF), which in turn supports ‘one carbon’ transfer. Tetrahydrofolates are required for de novo synthesis of purines, thymidylic acid and various amino acids and for post-translational methylation (epigenetics).
Very slightly soluble in cold water (0.0016 mg/mL at 25 °C), soluble to about 1% in boiling water. Slightly soluble in methanol, appreciably less soluble in ethanol and butanol. Insoluble in acetone, chloroform, ether, benzene. Relatively soluble in acetic acid, phenol, pyridine, solutions of alkali hydroxides and carbonates. Soluble in hot dilute HCl and H2SO4.

Dimethyl sulfoxide is a dipolar, aprotic solvent. Has been shown to accelerate strand renaturation (1-10% concentration) and is believed to give the nucleic acid thermal stability against depurination. By heating the solid form to approximately 30 °C, the product can be melted without harming it's stability.

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.

Paromomycin is a broad spectrum aminoglycoside antibiotic produced by Streptomyces rimosus var. paromomycinus. It has in vitro and in vivo activity similar to neomycin. It is effective against gram-negative bacteria, gram-positive bacteria, some protozoan species, and limited anti helminth. It is used to study bacterial protein synthesis at the level of 16S ribosomal RNA and 30S ribosome assembly. Paromomycin is used to study cytosine-cytosine (CC) mismatch-containing RNA molecules and is used to inhibit cryptosporidium infection of a human enterocyte cell line.

Guanidine Hydrochloride is a protein denaturant and thus having an important role in molecular weight determinations.
Guanidine Hydrochloride is a strong chaotropic agent useful for the denaturation and subsequent refolding of proteins. This strong denaturant can solubilize insoluble or denatured proteins such as inclusion bodies. This can be used as the first step in refolding proteins or enzymes into their active form. Urea and dithiothreitol (DTT) may also be necessary. Guanidine HCl is used in the isolation of RNA to dissociate the nucleoprotein into its nucleic acid and protein moieties. It is an inhibitor of RNase. Highly concentrated (6 - 8 M) Guanidine HCl solutions are used to denature native globular proteins. It apparently disrupts hydrogen bonds which hold the protein in its unique structure. However, there also is evidence suggesting that guanidine hydrocholoride may disrupt hydrophobic interactions by promoting the solubility of hydrophobic residues in aqueous solutions.
