Types
Fifteen laminin trimers have been identified. The laminins are combinations of different alpha-, beta-, and gamma-chains.
- There are five forms of alpha-chains: LAMA1, LAMA2, LAMA3, LAMA4, LAMA5
- There are four of beta-chains: LAMB1, LAMB2, LAMB3, LAMB4
- There are three of gamma-chains: LAMC1, LAMC2, LAMC3
Laminins were previously numbered - e.g. Laminin-1, Laminin-2, Laminin-3 - but the nomenclature was recently changed to describe which chains are present in each isoform. For example, laminin-511 contains an α5-chain, a β1-chain and a γ1 chain.

Famous quotes containing the word types:
“Our children evaluate themselves based on the opinions we have of them. When we use harsh words, biting comments, and a sarcastic tone of voice, we plant the seeds of self-doubt in their developing minds.... Children who receive a steady diet of these types of messages end up feeling powerless, inadequate, and unimportant. They start to believe that they are bad, and that they can never do enough.”
—Stephanie Martson (20th century)
“... there are two types of happiness and I have chosen that of the murderers. For I am happy. There was a time when I thought I had reached the limit of distress. Beyond that limit, there is a sterile and magnificent happiness.”
—Albert Camus (1913–1960)
“The American man is a very simple and cheap mechanism. The American woman I find a complicated and expensive one. Contrasts of feminine types are possible. I am not absolutely sure that there is more than one American man.”
—Henry Brooks Adams (1838–1918)
