ANSWER: |
Thank you for your enquiry. I have been in touch with the source of ab2101. They have informed me that under reducing conditions a 35kDa band was observed when using rabbit muscle. It mat be that the doublet that you are observing could be tissue specific isozymes that may have slightly different structures and therefore result in different MW bands by WB. I hope this information helps. Please do not hesitate to contact me should you require further assistance. |

I have already spoken to someone from tech services, and I was told to send an email to get the answer to my question. I have just purchased the anti-Lactate Dehydrogenase antibody (ab2101), and I need to know the expected molecular weight of the protein. Unfortuantely, this information is not indicated on the product data sheet. If someone would please reply to my e-mail, I would appreciate it. |

ANSWER: |
Thank you for your enquiry. The antibody will react with all "H" and "M" tetrameric isozymes of LDH. The expected molecular weight of the protein is 138kDa under non-reducing conditions and 35kDa under reduced. |

|
|||||||||
Is this antibody specific to any of the LDH isoforms (eg LDH-A, LDH-C) or isoenzymes (LDH 1-5)? |
|||||||||
ANSWER: |
The antibody will react with all "H" and "M" tetrameric isozymes of LDH. If you have any more questions, please contact us again. |

What is the molecular size of this product; lactate dehydrogenase (rabbit muscle). Please let me know as soon as possible. I want to sent out a publication by monday. |
|||||||||
ANSWER: |
138kDa under non-reducing conditions. 35kDa when reduced. |
||||||||
|
|||||||||
I'd like to use antibody against LDH, but in Drosophila. Do you think antibodies from mammals could work? |
|||||||||
ANSWER: |
The cross reactivity of this antibody with Drosophila has not been assessed, therefore we can't guarantee results. |

ab2101 staining Lactate Dehydrogenase in rat brain tissue sections by Immunohistochemistry (PFA perfusion fixed frozen sections). Rats were anesthetized and intracardially perfused with 500 ml of normal saline at room temperature, followed by 500 ml of ice-cold, freshly made 4% paraformaldehyde in phosphate buffer (PB, 0.1 M, pH 7.4). Alexa Fluor® 546 conjugated anti goat antibody was used as secondary.

ICC/IF image of ab2101 stained HeLa cells. The cells were 4% formaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal donkey serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab2101, 1µg/ml) overnight at +4ºC. The secondary antibody (green) was Alexa Fluor® 488 donkey anti-goat IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.
