Kpa penny
Kell 6
Jsa sutter
Kell 4
Kpb rautenberg
Kell 2
k cellano
Kell 7
Jsb matthews
This is immunogenic and exposure to K +?red cell resull the prod of anti K ab
K ag
k aag has frquency of 99.9% thats why hat is rarely encountered
anti k
Precursor substance of the Kell Ag
Kx
Present on wbc and rbc most individual
Kx
If Kx is lacking from red cell the cells have an abnormal shape which is
Acanthocytes
Acanthocytes in shape and reduced in vibo survival what ohenotype
Mcleod
The absence of Kx from leukocytes has been described with dse
CGD
Most common gene complex
Kell blood group
Reduced expression of kell ag
Mcleod syndrome
Mcleod syndrome ass with
HA and CGD
This is usually igg and require AHG
Kell ab
Rare reaction in saline
Kell ab
Implicated in Htr and Hdn
Kell ab
Is a very common ab
Anti K
Many ag in this system and some are alleles
MNSs
MNSs ass with
Gpa and Gpb
Four gene complexes
MS Ms NS Ns
Other alleles of MNSs
Mg, Mc, Mk, Mr, Mz, Mv, Na, T1m, Sj, S2
M and N ag amino acid composition
Glycophorin A
M ag amino acid
Serotonin
Sertonin
theronin
theronin + glycine
N ag amino acid
Leucine
Serotonin
threonine
Threonine + glycose
S, s ag amino acid
Glycophorin B
S contains what AA
Methionine
s contain what AA
Threonine
Acts as anti zN
Vicea gaminea
Ab of MNS are
Polar opposites
MNSs demonstrate
Dosage effect
Codominant allele in paternity
M and N
MNSs are discovered by
Levine and Lansteiner
MNSs differe from ABO ag in 3 ways
Ag found in red cells and tissue and not in secretion
Anti M and N resukt of transfusion and pregnancy
Anti M and N rarely occur naturally
Anti M and anti N ab are
Natural and Igm
Anti S, s, and U
Exposure igg
Transfusion reaction due to
anti S and anti s
Hdn due to
Anti s and anti U
Medico legal cases
Paternity
Paternity testing in Father NN ANTI M AND ANTI N
Negative and 3+
Paternity testing in Father MM ANTI M AND ANTI N
4+ and negative
Paternity testing in baby MN ANTI M AND ANTI N
3+ 3+
Usually Igm and room temp and some at AHG
Anti S ab
Destroyed by enzyme
Anti S ab
Rare Htr and Hdn
Anti S ab
Usually Igg and Ahg in MNSs
Anti s and anti U
Not detroyed by enzyme
Anti s and anti U
