What is the difference between Platinum technology and AccuPrime technology?
With Platinum technology, anti-DNA polymerase antibodies bind to the enzyme until the denaturing step at 94 degrees C, when the antibodies degrade. The polymerase is now active and primer extension can occur. AccuPrime Taq combines Platinum Taq (Taq + Platinum antibodies) with proprietary thermostable AccuPrime accessory proteins. The 10X reaction buffer contains the accessory proteins which enhance specific primer-template hybridization during each cycle of PCR.
Can I use MgCl2 instead of MgSO4 with Platinum Taq High Fidelity enzyme?
We strongly suggest using MgSO4. While MgCl2 may work in some cases, MgSO4 usually produces more robust and reproducible products, as sulfate is the best anion found for the Platinum Taq High Fidelity enzyme.
If I do PCR using the Platinum PCR SuperMix High Fidelity, can I use DNA-RNA chimeric oligos such as 5'-AGGCTTggau (lower case letters for RNA bases)?
PCR cannot be performed with an RNA oligo. RNA is not heat stable so the RNA part of the oligo will be degraded. In the presence of Mg++ (PCR buffer contains usually 1-2 mM Mg++) the rate of degradation is much faster.

Abstract
Identifying genes of agronomic importance in maize by screening microsatellites for evidence of selection during domestication.

'Crop species experienced strong selective pressure directed at genes controlling traits of agronomic importance during their domestication and subsequent episodes of selective breeding. Consequently, these genes are expected to exhibit the signature of selection. We screened 501 maize genes for the signature of selection using microsatellites or simple sequence repeats ... More
Pattern of diversity in the genomic region near the maize domestication gene tb1.

Domesticated maize and its wild ancestor (teosinte) differ strikingly in morphology and afford an opportunity to examine the connection between strong selection and diversity in a major crop species. The tb1 gene largely controls the increase in apical dominance in maize relative to teosinte, and a region of the tb1 ... More
Transforming growth factor-ß is required for vasculogenic mimicry formation in glioma cell line U251MG.

Both vasculogenic mimicry (VM) and transforming growth factor-ß (TGFß) are positively correlated with malignancy in glioma. Accordingly, we supposed that TGFß might be related with VM, and aimed to detect whether TGFß could influence VM formation in two glioma cell lines U251MG and SHG44, which were different in malignancy. We ... More
