|Description||Ceftiofur HCl (U-67279A) is a cephalosporin antibiotic, used to treat both Gram-positive and Gram-negative bacteria infection.|
Ceftiofur can downregulate tumor necrosis factor-alpha (TNF-alpha), interleukin-1beta (IL-1beta), and interleukin-6 (IL-6), but did not affect interleukin-10 (IL-10) production. Ceftiofur significantly inhibits extracellular signal-regulated kinase (ERK), p38, and c-jun NH(2)-terminal kinase (JNK) phosphorylation protein expression in RAW 264.7 cells. Ceftiofur also inhibits p65-NF-kappaB translocation into the nucleus in RAW 264.7 cells. 
|In vivo||Ceftiofur treatment is associated with a significant decrease in rectal temperature and diarrhea in neonatal calves. Ceftiofur results in a significant decrease in fecal shedding of Salmonella organisms in neonatal calves.  Ceftiofur hydrochloride (intrauterine (i.u.)) reduces the prevalence of positive uterineculture in cows with clinical endometritis (29.0 vs. 51.4%) and reduces the overall prevalence of Arcanobacterium pyogenes (1.0 vs. 7.6%) at 51 d in milk (DIM) . Ceftiofur hydrochloride reduces the prevalence of uterine infection in cows with clinical endometritis, and the prevalence of A. pyogenes, but does not affect the prevalence of subclinical endometritis or fertility of dairy cows already receiving PGF(2alpha).  Ceftiofur hydrochloride (i.m. injection) results in C(max) of 11.8 mg/mL at 1-4 hours after injection, the mean area under the curve (AUC) of 216 m g x h/mL in pigs.  Ceftiofur hydrochloride （2.2 mg of CE/kg, SC or IM, once daily for 5 days） is efficacious for treatment of acute postpartum metritis (APM) in dairy cows. |

1.Please make sure the liquid is clear before adding the next solvent.
2.Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and SDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and SDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
