The answer, get another supervisor, she is obviously not up to it. -----Original Message----- From: histonet-boun...@lists.utsouthwestern.edu [mailto:histonet-boun...@lists.utsouthwestern.edu] On Behalf Of Jenny Vega Sent: 06 October 2011 00:04 To: histonet@lists.utsouthwestern.edu Subject: [Histonet] Difference between Neutral Buffered Formalin 10% and NB formaldehyde 3.7 to 4%
Ok I want to know the diferrence between Neutral Buffered Formalin 10% and NB formaldehyde 3.7 to 4% . I was taugh at college that they were the same thing and in the book from Frieda Carson it says that but my supervisor swears they are different chemicals. In the laboratory she has used 10% neutral buffered formalin all the time, but when we ran out of it we were sent NB formaldehyde 3.7 to 4 %she sent it back and we were sent NB formaldehyde 3.7 to 4% once again. She says that 10% NBF is more concentrated and pure than 3.7 to 4 % formaldehyde and that the tissues are going to putrefied if they are put in that solution. Am I wrong or is she wrong? thanks _______________________________________________ Histonet mailing list Histonet@lists.utsouthwestern.edu http://lists.utsouthwestern.edu/mailman/listinfo/histonet _______________________________________________ Histonet mailing list Histonet@lists.utsouthwestern.edu http://lists.utsouthwestern.edu/mailman/listinfo/histonet
