Immunoenzymatic colorimetric method for quantitative determination of thyroxine (T4) concentration in human serum and plasma.
T4 ELISA kit is intended for laboratory use only.
Chlamydia Trachomatis IgG/IgM
Chlamydia Trachomatis IgG/IgM
C. trachomatis is the most frequently sexually transmitted bacterial
microorganism. It causes urethritis in men and cervicitis and salpingitis in
women. Infants from infected mothers may develop inclusion
conjunctivitis and pneumonia. The diagnosis of Chlamydia trachomatis
infection is made either employing cell culture or serological techniques.
The most common serological test is the indirect microimmunofluorescence,
but ELISA techniques are easier to carry out. In the
assays is used COMP (Complexes of Outer Membrane Proteins) of C.
trachomatis, free from LPS which is responsible for most cross-reactions
with other Chlamydia species.
Chlamydiae are nonmotile, obligate intracellular bacteria with
a unique life cycle that includes two phases: reticulate and
elementary bodies. Chlamydophila pneumoniae causes
infections of the upper and lower respiratory tract.
Trypanosoma rangeli is a flagellated protozoan belonging to
the family Trypanosomatidae. While it is considered nonpathogenic
for the vertebrate host, it produces pathogenic
effects to the triatomine vector population, such as difficulty in
the molt and retarded development of nymphs that can lead to
their death. T. rangeli is mainly transmitted by the bite of an
infected triatomine. It shares with Trypanosoma cruzi, the
aetiological agent of Chagas’ disease, multiple biological and
immunological features, such as its geographical distribution,
reservoirs, vectors, vertebrate hosts and antigenic
determinants. For this reason, it is a common source of
cANCA IFA plus is used for the sensitive qualitative and semiquantitative
determination of IgG antibodies to neutrophil
cytoplasmatic antigens (ANCA) in human serum using indirect
immunoflorescence assay on ethanol fixed human granulocytes for
the differential diagnosis of systemic vasculitis (SV).
Varicella-Zoster virus is an enveloped, icosahedral, double
stranded DNA virus with a diameter of 150 to 200 nm. Varicella
(the primary infection) occurs most frequently in children and
is characterized by a generalized vesicular exanthema. Zoster,
caused by the reactivation of the latent virus, occurs in adults
and consists of a painful eruption of vesicular lesions
accompanied by inflammation of nerve ganglia.
Toxoplasma gondii is an obligate intracellular protozoan parasite that is
distributed worldwide. Human can acquire the infection by accidental
ingestion of oocysts from cat feces, by ingestion of infected meat, in utero
or by transfusion or transmission by organ transplant. Most infections are
bening although severe symptoms appear in immunosupressed patients or
congenital infections. Women infected during the first trimester can have
spontaneous abortion and hydrocephalus. Disease acquired later in
pregnancy causes less severe illness.
IgM antibodies appear 5 days after infection and fall to low levels within
weeks or months in the majority of patients. IgG antibodies appear weeks
after infection and persist for the rest of the life.
CytoBead® ANA is a reagent set for the determination of IgG
antibodies against nuclear and cytoplasmic antigens in human
serum for the diagnosis of systemic autoimmune diseases. This
determination is using indirect immunofluorescence on fixated
HEp-2 cells and allows furthermore the ANA differentiation by the
use of antigen coated beads (dsDNA, Scl-70, SS-A/Ro60, SSA/
Ro52, SS-B, CENP-B, Sm, Sm/RNP).
ANApro is used for the separate semi-quantitative determination
of autoantibodies to nuclear and cytoplasmic antigens (dsDNA,
RNP, Sm, SS-A, SS-B, Scl-70, CENP, Jo-1) in human serum or
plasma for the differential diagnosis of systemic rheumatic
Bacteria of the genus Borrelia are highly motile spirochetes
with a Gram-negative bacterial type cell wall, that grow under
microaerophilic or anaerobic conditions. Borrelia burgdorferi
sensu lato is the causal agent of Lyme disease and includes
three human-pathogenic species: B. burgdorferi sensu stricto,
B. afzelii and B. garinii. The three species are present in
Europe, while only the former is found in North America. They
are transmitted to humans by the bite of ticks.
Mycobacterium tuberculosis is an strictly aerobic,
nonchromogenic, slowly-growing, acid fast bacillary bacterium.
Humans are the only reservoir of M. tuberculosis, an obligate
pathogen that is transmitted by airborne particles and may
remain latent for years before causing an active tuberculosis.
Bordetella are small, aerobic, Gram-negative, coccobacillary
bacteria. Bordetella holmesii is associated with bacteremia,
endocarditis, and respiratory illness, mainly in
immunocompromised patients and has also been detected in
nasopharyngeal specimens from patients with a pertussis-like
illness. Little is known about the normal habitat of B. holmesii
and its potential mode of transmission.
