Product Introduction

GENERAL DESCRIPTION 

Sulfadiazine (SD), one kind of broad-spectrum  antibiotic, is  effective  for  anim al  production  for  its   excellent  antibacterial  and pharmacokinetic properties . It has  been widely used in different lines   of  poultry,  cattle,  agriculture  and  beekeeping.  However, Sulfadiazine is  prohibited in m os t countries  as  its  residue may cause serious  side effects , such as  hematotoxic. Therefore, it is possible that Sulfadiazine residues , after use in illegal practice, may lead to a ris k for consumers .

PRINCIPLE OF THE TEST
Competitive  assays   are  primarily  used  for  testing  small molecules . If Sulfadiazine is  present in the sample it will therefore bind with the conjugate and will be labelled. As  the sample migrates along the membrane and reaches  the capture zone an excess  of labelled antibody will bind to the immobilis ed antigen so that no visible line is  produced. The bound conjugate will then bind to the antibodies  in the control zone producing a vis ible control line. A single  control  line  on  the  mem brane  is   a  positive  result.  Two visible lines  in the capture and control zones  is  a negative res ult. However, if an excess  of unlabelled Sulfadiazine is  not present, a weak line m ay be produced in the capture zone, indicating an inconclusive result.
