1. Blood Typing Lab

2. (1) Antigens & Antibodies
Membranes of RBC’s contain unique I.D. Tags (Antigens)
Antigens are membrane proteins
Unique antigens bind with Unique antibodies
Antibody: Protein produced to bind with foreign cells to stimulate immune response of lymphocytes.

3. (2) Agglutination Agglutination = Binding of antigens with antibodies.
Causes a clumping of factors.
Looks like a thickening of blood.
When blood-cell antigens bind with their matching antibodies….. AGGLUTINATION!

5. (5) Blood Typing Lab Purpose: Procedure:
Solve the crime scene and identify the suspect
Test crime scene blood and blood of all suspects (W, X & Y)
Procedure:
Mix blood with “Serums” (anti-A, anti-B & anti-Rh)
No Agglutination = Does NOT have those antigens
Agglutination = Those antigens present

6. (8) Rh Factor
Blood Type can either be “Positive” or “Negative” for the Rh factor
Agglutination with anti-Rh Serum = Rh+
No Agglutination with anti-Rh Serum = Rh-
