- MCQ. It is possible to incubate your tissue with two different primary antibodies simultaneously. If this is done, it is imperative that you can track each primary antibody with a different color. For example, one secondary antibody is tagged with Alexa488 which emits as green and another secondary antibody is tagged with Alexa 555 which emits as orange. Which of the following immunohistochemistry protocols is appropriate? a. Using Rabbit anti-GFAP and Rabbit anti-S100beta, followed by anti-rabbit Alexa 488 secondary antibody b. Using Rabbit anti-GFAP and Chicken anti-S100beta, followed by anti-rabbit Alexa 488 and anti-chicken Alexa 555 secondary antibodies c.

Both polypeptide components of the alpha:beta TCR are members of the immunoglobulin superfamily, and each of their domains share structural similarity with regions of antibody proteins. However, due to the different functions of TCRs versus antibodies, the overall domain organization of the TCR is not the same as for an antibody. In the figure below, describe three features that are incorrect illustrations of the alpha:beta TCR.arrow_forwardName the two types of antibody light chains.arrow_forward
- The ends of each heavy chain and light chain in an immunoglobulin make up the antigen-binding sites. The end of one of these chains is shown here. Biochemists tend to classify protein structures into four groups: mostly alpha, mostly beta, mixed alpha and beta, or neither alpha nor beta. Based on the model shown here, how would you classify this part of the immunoglobulin protein? The loopy polypeptide segments at the very top of the structure shown are the segments that actually contact the antigen. Would you expect these binding segments to be rigid or flexible?arrow_forwardBriefly describe the structure of an antibody and relate this structure with its functionsarrow_forwardstructure of an antibody.
