LD50 of Subcutaneously Injected Alpha-Dendrotoxin?

Hello. I'm just wondering, what is the LD50 of subcutaneously injected Alpha-Dendrotoxin? It can be in rats/mice or humans, but humans would be extra helpful. Thanks!

How to find the longest contiguous maxim-gilbert sequence ever established?

I need to find the longest contiguous sequence ever established using the maxim-gilbert (chemical degradation) method. I couldn't find any useful references to this in literature. So the only other way I can think of to do this would be to someh

I was wondering whether there are any free Botanical Identification Keys Online which can be accessed on my phone. I'll be pleased if somebody can help ! :-)

Bio Project, Housekeeping promoters, high C-G count, vs tissue specific?

I have a research biology project to do, one part that I'm doing is essentially comparing the sequences of different organisms and based on the sequences am describing whether that gene has a housekeeping promoter or a tissue specific promoter.

I am a non-biologist (my formal biology education ended with a high school class) who is slowly educating myself in an ad hoc manner by reading various books that seem interesting (such as Beak of the Finch and Botany of Desire) and by

Effect of KCl on Smooth Muscle - Biphasic Response

Hi, We did a lab where we tested the effects of different drugs on intestinal smooth muscle, and for the lab report we have to explain the physiological mechanism underlying the observed effects. One of the drugs used was KCl, and according to t

Am I correct in thinking that because ERB (which is downregulated in cancers) downregulates c-myc ( c-myc regulatesthe cell cycle and transcription) and so this is a form of epigenetic modification?
