PLTS:-days, temp, with-open: pooled, apheresisGranulocytes/washed-time good for with no-washed preventsIrradiated -days -prevents

A

PLTS-light spin removes rbc, heavy spins down wbc/plts-5 days, 20-24 w/agitation-4 hrs plts pooled open-24hrs aphresis openGranulocytes: 24hrs, 20-24,no agitationwashed rbc: 24hrs, prevents allergy to plasma proteins in IgA defIrradiated: 28 days, prevents GVHD

A

Backbone is Gal with Fuc off bottomGenes add onto Gal to the left…O gene is inactive, H is unmodifiedhas fuco-syl-transferase/fucoseA has N-acetyl-galac(NAC)B has D-galac

21
Q

Bombay phenotype is..antibodies in serum..Phenotype with absense of Rh…

A

absense of ABO ag, Ohhas A,B,H-type as O-not agg w/anti-H, no HRhnull is absense of Rh ag

22
Q

H ag greatest to leastgreatest, least

A

greatest H is O, least is Oh(none)A2>B>A2B>A1>A1BO>A2>B>A2B»A1>A1B>Oh-A2>B-more A, B less H so A2>A2B-A2>A1

Q

Se: expression ABO ag in BF, secretor status-dominant, 80% have Se geneSe codes for these three…-need….to have A or B-Se doesn’t code forLe: adsorbed onto red cell, in saliva/plasma-need Le to make…-need.. to make…

A

Se codes for H, then A and B, doesn’t code for SeLe:-need Le to make Lea-need Lea to make Leb
